Sorry you need be a bit more pacific, i swaped my loom.

What are you doing?

ABY with ABY fuse box?

[s2martyn]

yes,its aby engine loom to aby fuse board

[terrybullwon]

and the wires... what connections are on them? spades? or rings?

Try the rs2 schematics on s2central.net. I found that they had more in common with my ABY loom.

[terrybullwon]

You would think, but the looms have so many changes.

@s2martyn - I'll look at this one later today / tonight for you. Meantime - please be more specific on where these wires are coming from... Can I assume its ABY loom into a normal 80/90 fusebox ?

Some initial thoughts... Buzz them out to check properly - don't take this as gospel - there are some wire color mistakes/changes thru the years...

1 - that red/black might be track 108 for afterrun

2 - green/black might be output from fuel pump relay shown on Sheet - see fuses S24 and S28
It might also be the feed via S32 to the coils on track 74. I have a note that I've seen green/black uses there as well as black
Other option is track 65 where it should go to T5h/1 if you have aircon fitted.
Final though is track 99 for hi temp switches

3 - is that grey/yellow or grey/green ?
Check out S25 at the fuel pump relay on sheet 2

4 - Pretty sure this is T5h - a 5pin red connector behind the dash used as follows:

1 = green/black on Track 65
2 = black/yellow on Track 109
3 = empty
4 = blue/white on Track 68
5 = empty

Hope that helps... Do you know how the fusebox code letters line up with schematics OK ?

thanks paul was going to pm you about this
the car now runs fine...was the first time i have heard it since the engine was removed from the s2 avant...sounds very nice breathing through the gt35 and the 3" exhaust i made sounds suprisingly quite

back to the wires for future reference
i used s2 loom and s2 fuse box
the red 5 pin conector with only 3 wires going to it is definatly aircon(so not used for me)
grey/yellow goes to afterrun
black/red is ecu permant power
black/green is switched off the fuse board
