So according to the pinout pdf you should have voltage between 1A and 4A/B/C or D all the time and 1B and 4A/B/C/D with ignition on....have you verified that with the multimeter?

im getting nothing except a few have 0.**v like nothing noticeable :S cant work out from that diagram which is plug 1 and which is plug 4 lol but on either testing the fronts and backs there is no 12v going there :S

If I\'m reading it correctly I\'d say plug 1 should have 22 pins plug 4 should have 26 pins. If that is right then the first 4 pins on plug 4 are Ground pins so you should see continuity between them and metalwork. If you have a wiring diagram you should be able to suss what plug is what though.

I should start by grounding the multimeter on the shell to try and verify any voltage on the pins and then try it on the grounds of the plug.

The plug with the loose wire is Plug 1. So, looking at that plug from the wire side (with the loose yellow wire towards the bottom left). You should have 12v positive at all times to the wire at the top right.
The wire at the bottom right shouldn\'t get any voltage until you turn the ignition on. Once on you should see 12v positive.

Are you getting either of those?

right worked out plug 1, pin a that should have a constant 12v and it doesnt! now the wire goes up through the bulkhead down the passenger wing and in to the bay but where it goes there im unsure... does anyone know or can you make sense of the diagram in the workshop manual??

captainbizzaro · July 29, 2010, 09:52:38 PM

....and pin 3 should see 12v when you twist the key to the crank position. Do you have a PDF wiring diagram for your year FD?

MaLicE · July 29, 2010, 10:05:06 PM

i have the fd wiring diamgram yeh... and im getting nothing on the other pins well the switched live isnt... the wiring diagram is like hell on a bad day to try and work out lol!

That yellow wire on the on the FC Apexi ecu is for the speed pick up. It goes to the cruise control switch on the dash. But that is for the FC not FD.

According to the wiring diagram it should go to the 10amp Room fuse under the driver\'s side dash.

thats strange as it goes through the bulkhead and down the big bundle of wires that go under the pass wing...
