White is DME (main engine) relay
Orange relays are fuel pump and lambda sensor heater. Fuel is the one with a green/purple wire going to pin 87.
Spare wire in injector loom is a left over from when E30s had two pin brown temp. sensors. The same wire that's present on pin 20 of the engine loom socket on some cars that causes a burn up when a later engine loom is fitted.
ICV: red/white is 12 volts + from the DME relay, other two are the signal wires for the balanced armature design.
TPS: brown is earth, brown/blue is idle, brown/black is WOT.
