hello to anyone that can help.
i have recently put a newly rebuilt and forged rs turbo engine into my mk5 cab.
that was the easy part.
now im onto the wiring loom.
i tried making one of my own using a guide off one of the escort sites
that didnt work.
i then bought another one and tried again.
this time i managed to get somthing right i.e i have the fuel pump priming sometimes, but i cannot get any voltage at the coil at all in fact im getting negative 12.36v on both the green wires and also on the black wire
is there anyone who could possibly make and label loom for me so i could connect it to the various earths and lives and try again because im thinking that i just keep getting somthing wrong.
any help would be great.
thanks to everyone with ideas
