recently bought an ofac loom that had been cut out of an efi xr3i need to sort some wires out on it. and it will be going in my s2 with my ofam ecu.

Pin 57/37 idle speed valve & injectors & Speed sensor & Boost control (tbc) they get joined into 1 wire that go to the fuel injection relay back out into the fuel pump relay then off to engine loom. does this seem right?

Pin 21 idle speed valve. come out then splits straight into 2 wires that run to 2 different plugs both of the black wires then run into the engine loom does that seem right?

lastly coil pack plug where does the black wire go to mine is currently cut and there no cut wire the other side.

cheers
