S1 C34 Stag S2 Neo swap

[Pantista]

hi all

I have a Series 1 Stagea that had RB25DET auto, motor died, SO ive got a RB25DET neo manual with matching Loom,ECU.(Motor is in car now)

I understand that the series 1 fuse box is different and after searching have been told that ABS, Atessa and AC wont work.

Has Someone wired this correctly to fix these issues, am wondering if i just have to re-pin the body plug to suit the series 1 pin out.

sorry if newbie question struggling to find info on this.

Thanks all.

Just checking - your S1 is AWD - is your Neo  motor and gearbox also AWD?

ECU pinouts are not that different.

Here are some (not all may still work):

yeah both are AWD my manual is AWD too.

ECU pin outs look the same don't see why they shouldn't work. both are the grey style plug.

I haven't seen if the body plug however is different between series 1 and a neo series 2

the ABS module is different between s1 and s2 but possibly i should be able to cut and colour match the s1 plugs to the S2 loom. just cause plugs seem to be different shape that is all.
