ok , lets start again. sorry im stressting over it as i dropped the engine in a few days ago.
Pic 1 im asking is this ALL the engine bay earths? or are there more ive missed off (lamba sensor earth is attched same place as that other small earth thats attched to the bulk head)
pic 1 again, im asking what the point in this plug is?
Its basically 2 plugs that come thourgh the bulk head and plug into each other. There under the original loom take so there in teh bay from standerd if you get me. I cant understand why there not behind the bulk head. And theres a brown/green/black wire and a brown/green AND black/black wire, BUT they plug together perfectly.
pic 2 is just showing the lamba sensor earth and another earth by the bulk head
pic 3 is a plug under the dash , that i have no idea where it goes. I dont know if its not meant to connect to anything or what its just there!
pic 4 is 2 more plugs under the dash whcich i have no idea where they go. I belive one goes to the speakers as i dont have them in at the moment. but whats the white one do?
pic 5 i think this is also a speaker plug but im not sure. so i thought id may aswell ask...
pic 6 i meant to ask but forgot is that the right amount of plugs that connect to that plastic bracket? also theres a positive red wire that runs directly from the battery to that black plug in that brack its a spade connecter. I was wondering what this is for?
and thanks

read through what you have written - and then ask yourself how the hell anyone will know what you are on about.
the 3rd picture show the engine diagnostics wiring
the 4th shows what i think is the glovebox light plug
"also what is this plug for? they come into the engine bay the same way and plug into each other. whats the point in that?"
what are you on about? youve just written over a photo! if you are refering to the 5th photo in your post - THATS THE FUSEBOX CONNECTORS!
if you help us out in making your question legible - we might be able to help!

In the first picture the top left, bottom left and bottom right are the standard earths. The top right is one that been added by somebody, one of the wires might be going to the lambda earth though the usual thing people do with this is connect straight to the battery earth terminal.
-
Lambda sensor earth should be connected to the inlet manifold where the block connectors are held.

Ive read this 4 times and i havent a clue what the fuck your on about. and you havent highlighted it in the pic - AT A COMPLETE GUESS - are you talking about the wires to the ignition amp?
Picture 2 is the wrong earth
Picture 3 isnt clear enough
Picture 4 is the diagnostics wiring and isnt connected to anything unless you plug a computer into it to do diagnostics.
picture 5 you answered yourself and is speakers
picture 6 looks correct and there isnt anything connected to the white plug unless you have foglights and the positive wire you are on about is anyones guess because - again you can see what your on about
YOU NEED TO BE CLEAR WITH YOUR QUESTIONS AND YOUR PHOTOS!

you know what youngprodigy. Fuck you knob.
Jesus christ
Im asking wft that plug is thats comes through the bulk head , i was hoping someone would reconise it.
Your a fucking dick mate sorry.
-
Calm down Jake. You clearly aren't going to get any assistance by slating the people trying to help you.
-
Man , he asked me to write it out again and i did i went though every picture explaining what i was asking. Then he went off on one again.. pure prick.

what do you mean i havent highlightend it? Its right in the center! next to the rocker cover.........???!!!!
-
yer because circling 5 things in a photo obviously means you were on about the middle one. if you had said it was the middle one - I'd have said the only connector in that area lives under the inlet manifold connected to the idle control valve.
if you start getting angry about people asking for clarity - don't be surprised if no one wants to help. like I said - get a better photo of what wires your on about coming out of the bulkhead.

Pic 5 is defently a speaker connection.
You said "pic 3 is a plug under the dash , that i have no idea where it goes. I dont know if its not meant to connect to anything or what its just there!"
According to haynes manual it could be the connection for the LH rear speaker or i have just checked another page and it could be Self Diagnosis socket. More than likely to be diagnostic socket.
Pic 4, Brown/red is a diagnostic plug as mine is not connected to anything.
The yellow one in my car is the same, not connected to anything. In manual it could be a diagnostic socket that is not used.
-
Thanks for your help jezza :)
Ill check those earth's because when i turn my ignition on i have no fuel pump prime , but the ful pump does work as ive tested it, also the car has no spark and ive tried 2 coil packs and 2 dizzy and no luck. So do you reckon maybe a dodgy earth is stopping the fuel pump working and it not ssparking? But all dash lights do work , headlights work , horn works , everything else seems to work.
Also any idea what that plug is thats circled in the middle of that pic of posted. It comes into the bulk head and just plugs into each other.. i cant see the point in this, but iits obviously there from scratch as its under the original loom tape.
Thanks mate

The 1st pic?
-
This is what my bay looks like
(http://i443.photobucket.com/albums/qq157/jezza-3/DSC01150.jpg)#
But im not sure about them wires.
What colour are they and how many are there. I will go have a look around if it doesnt get too dark soon.
-
if your fuel pump isnt working its more likely to be due to a dodgy fuel pump relay rather then any of them wires at all.
the ecu turns the pump on and also provides the spark aswell - have you checked the ecu relay?
Do you have a multimeter?
-
i've read this a couple of times, and im not quite sure what questions are left outstanding? Might have been easier if you'd wrote the questions underneath each picture it related to? Anyhow...
Pic 3....Speaker or Brake light switch?
If all of this is going in a mk3,why have you changed all of the interior dash loom,i thought they were all the same?
-
100% not a brake light switch!
pic 4 is the diagnostics
pics 5 and 3 i think are both front speakers left and right - as they are both sleeved in that foam stuff - my haynes says that the wires should be RED+ BROWN/WHITE and the other BLUE + BROWN/BLUE
is that wiring red and brown/white on pic3
this may help you chase what the other engine wires are

save it and then view it for full size and this will be deleted in the next 2hrs as im not getting caught for posting this

If your fuel pump is not priming and you have no spark try swapping the plugs near the coil. They fit together two ways. One way works and the other way causes your symptoms.
-
Alex that one got me last year. thats when I learned: no matter how well those plugs fit together if the wire colours are wrong it won't flippin work haha. good shout.

mate what plug is this exactly? this sound exactly my problem.....!
If possible text me the plug with the wire colours please 07502243812.
Im that desperate to get it running ahha
-
heres a better picture of this plug.. just for you prodigy ;)
Anyway:
(http://i47.photobucket.com/albums/f183/bmxer05/Photo0451.jpg)
listen carfully haha , on the left of the plug the colours are black , green and brown and the other side of the plug the wire colours are black, green AND black , and brown
The plugs come through the bulk head toghether and connect straight into each other perfectly.. and i cannot find another plug for them to go into. Now either im missing something or this is right? which i still dont see what the point of them is in coming through the bulk head.
Hope you understand , thanks
-
3 wire plug to the coil is black, black/green, and brown. As shown in the Haynes manual, which youngprodigys posted for you. And confirmed (or so I thought!) by my shonky labelling.
The other 3 wire plug which is exactly the same but doesn't plug into the coil is black, black/red, and brown - the other half of this connector is black, green, and brown (I believe this is correct, my loom is off the car, and I now hope it all goes back together OK!).
-
Man i had it the wrong way around , havent checked for a spark yet as my battery is dead but my mate should be here in a min and i can borrow his.
This should be FAQ because the plug look as if they match which they do but there still wrong.
Thanks alot for this , ill get back to you within the hour and let you know the good or bad news thanks mate :D
-
It's the most common wiring mishap when doing engine conversions or refitting, comes up time and time again, so yeah defo needs a FAQ for it. ;D :D
-
hmm still no fuel pump prime , but turned the engine over slowey and couldnt see a spark. But i dunno weather thats because the engine was turning over so slowly...!
prodigy , when you say change them fuse boxes your mean them little silver boxes next to the ecu? i do have 2 spare ones of those..!
-
THAT IS THE IGNITION WIRING! i did say mate "at a complete guess" earlier. if you cant see you cant say!
theres 2 connectors by the ignition coil, swap them over as suggested!
if i remember rightly the connectors supplys the following
One of connectors provide the following
1-power to the Ignition amp
2-Earth to ignition amp
3-Spark signal
the other connector provides
1-power to ECU
2-Earth to ECU
3-Tacho signal to clocks.
both are identical plugs and if im right next to each other on the ignition amp block. mine wiring has been hidden so i cant just look anymore.
Itshould make your fuel pump prime as you will have power to the ECU. if not you will need to check you have power going to the ECU. do you have a multimeter? and also check the fuse above the little silver boxes (there called relays btw)
-
i kinda new they were relyas just wernt 100% sure on it as i cant remember , hearing them click etc.
Anyway , we now have spark thanks to changing those plugs around.
And we now have fuel pump prime thanks to me taking out the fuel pump cut off switch that some idiot decided to put in the car before i bought the shell..
thanks
-
So is it starting then?
-
Been out in it all night , my fist G experiance.
Oh my hahahaha what a lil beastttttt! so quick
FAQ is needed about them plugs. Because it put off driving my car for a week. Dont want the same to happen to someone else.
-
It's already covered mate. Reading Haysey's (rather good) G40 Engine Diagnostic Guide in the Engine and Transmission FAQ would have taken less than a week! :D
Glad you enjoyed your first drive though!
-
haha only if i noticed that in the 1st place. TBF i did look but didnt think of looking in that thread.
And cheers man , just need to sort the oil pressure switch out now. Bleeps it tits of when you give it a little bit of death. Any ideas?
The oil pump IS working as its flicking it around in the rocker cover when i take the oil cap off.
Or is it possibly something to do with the fact one of my oil pressure switches is off a mk2?
