My Mk1a V6 Wiring Diagram

***This is just a guide, check all your wires before connecting yourself etc....***

This is to supplement the existing write ups and various threads, here is the wiring on my 1986 mk1a so far.



Available as a bitmap with better colours here

I think you'll need to hook up the other alternator wires like I had to yesterday.

look around your auto box plugs,you know the redundant ones that should be left over now? one of those plugs has the white wire from your alt on it,when you find it do a quick continuity test back to the alt plug to verify its the one.When you have established its the correct one run it into the boot and onto the white/red wire on your N1 connector.

The other wire should be blue/red stripe.... this is on one of your v6 white plugs in the boot,again do a conty test back to the alt plug to confirm.

Connect this one onto the black/yellow stripe wire in your N1 connector.

Your alt will now charge :thumbsup:

Hmm interesting, will check tomorrow and update diagram if necessary.
I have a couple of other bugs to sort out, lack of dash warning lights etc.

Those two wires will give you the battery and charge lights when you go to the ignition stage before starting the engine :)

ok, updated cheers :)

Outstanding work. Sticky-ing the thread now :thumbsup:

If it's not quite finished yet could you stick a bid red label at the top to say work in progress or something similar? I'd hate to see a newbie blindly copying it and then blaming you if he had a problem!

Cheers,

Owen.

Good point, done :)

I'll wait for the "Paul Woods seal of approval" :thumbsup:

theres a problem with that diagram on the check engine light,pin 4 on the 4th ecu plug is for CEL (usually green) and that should go to pin 1 on the N1..... in the diagram you have pin 1 on the N1 going to pin 9 on the 4th ecu plug which is wrong.

Also it might be worth adding pin 1 on the 4th ecu plug joined onto pins 12 and 13 as this is 95% the case with v6 ecu's,yours is the rare exception that we have only found once so far with no pin 1.

Other than that its a great diagram :thumbsup:

Jeez Paul, what did that take you? 30 seconds to diagnose a complete V6 wiring diagram? We are not worthy...

Added you as number 11 to the swap register. Bloody well done mate!
