Title: Wire colour/location confirmation needed
Post by: 05omegav6 on 15 December 2011, 10:12:26

Currently wiring in MID. Book of Blocks says:

Current Track 846, MID Pin 27 SWBR 0,5 leads to Current Track 257.

Current Track 257 being Pin 32 on the ECU. All clear as mud so far. ::)

I've found a SWBR wire on the bottom/lower plug on the ECU...

BUT, I cannot pinpoint this wire where it comes through the bulkhead, it just doesn't exist :'(
Had a similar issue with the wiring for the coolant and washer levels, but the colours at the plugs match the (short) MID loom, so was able to simply connect the two ends.

Before I go assuming and connect the MID SWBR to the ECU SWBR and blow summat up, can some one please confirm the colour/location (and how to correctly identify the ECU pin numbers) of the ECU output to the MID. Haynes only covers the 2.5/3.0, not the DBW V6's, so just want to be sure :-\

As ever TIA, Al. :y

Problem is that the cars are built up of several loom sections and a section may have the spare wires in but another section not - as you have just found out. Bypassing is the only thing you can do TBH.

Thanks for that... My lower plug has nothing at Pin 3, whilst the Pin numbers are reversed for the upper plug. So a bit confuddled now :-\

On me lappy again now (TIS doesn't work on Touchpad), what pin is it you are unsure of?

Ok need clarification of the MID Link from the ECU and wire colour as pic above doesn't match vehicle. :-\ Pin 3 on the top plug as you look at the ECU is populated by  BRBL, Pin 3 on the lower ECU plug is blank but there are a couple of SWBR wires on both plugs. Reg is OU54AEW. :y

TVM :y

Pin 3 on X86 is BKBN going to pin 27 on MID.

Pin 3 on X85 (BNBU) seems to be an injector :o


HTH

As you lift the ECU plate out of the relay box, is X85 the top plug? :-\

Yet another plug to retrofit wiring to ::) Does explain why I couldn't find the wire inside the bulkhead though :-\

Sadly Pin three on X86 is as bare as a tree in a nuclear winter :P
