If it makes you feel any better my swap over hit a f**k off sized brick wall tonight. Turns out the injectors are wired straight into the ecu, can't just unplug them somewhere and use the complete loom from the sil.
So we decided to use the engine part of your loom that had been sliced off, and the ecu part of my loom, which we had to slice off in exactly the same fashion. Do you think all the wires in a Ceffy loom match up with what I presume to be the 32 loom from my car? NOOOOOOOOOOOOOOO of course f**king not.
So where it was left tonight was we have 2 complete looms, both sliced cleanly in half. Of the 20ish wires on both looms, the easy to match up (only 1 of that colour) ones have been soldered together, the slightly harder ones (theres like 3 or 4 solid black wires coming from each loom) have just been left until one of us doing the job can be f**ked having another crack at it.
Now to search the shit out of the forum and see if I can come up with ANYTHING that is going to help us identify which ones to join to get the c*nt running. Alternatively, anyone have half an idea about wiring, familiar with 32s/ceffys/RB20s and want to lend a hand for some booze?
