ive taken all the pastics out and the dash and started to trace the wires, ive found that some wires arent there that need to be and some are where no wires are suppose to be.. thats going by wiring diagram. so do i just need to unplug the wires and re-reoute some new wires?

what are you doing ??

im planning on redoing the wiring on the whole crx. its a ED with a teg b16a swap.but the guy who done the swap pretty much just added the teg loom into the car, so theres 2 pretty much full looms running. then the guy who i got it from has had a go trying to fix it as the vtec wasnt engaging.

so far im just tracing all the wires from the wiring diagram but as i said, ive found some wires arent there, while others exist that shouldnt.

from what I remember the PR3 is wired different to the PWO on a few pins but this link might help, its based on a ED9 AUDM CRX in with EF9 B16A, PWO ECU

thanks for the link, had a good read of it, but its kinda hard for me cos looms have already been chopped up. so i have to go over the whole thing anyway and start again.

Would a jdm pr3 ecu differ in any way?

[ECU-MAN]

ecu pins are the same,

[qikteg]

do wiring colours change across the domestic markets (USDM, AUDM, JDM etc etc)?
