Thats a side light plug.
Paul, i have a ford workshop manual for the RS, which has wiring diagrams for the ecu's.
I'm also pretty good with wiring if you need me to pop over the weekend.
Matt.
Nope both wrong
mk3's never had a fan over ride wire, i found out today that it is actually..................
The fan thermostate switch wire.
Duh, i should of known
Matt thanks for the loan of yourself but, i think you may not be needed. Although as of tonight it still aint running properly.
We managed to get it going for about 5-7 minutes today, running nicer than yesterday.
But it just wouldn't idle properly, almost sounds as if its missing or the timing is well out. The time it did start today the timing on the dizzy was fully advanced.
The crank pully and cam pully are both correct with the timing and when all is TDC the rotor arm is in the correct place.
Its really weird
Also the battery is on its last legs with holding charge, so its on charge overnight again tonight. But a new one would prob help quite a bit.
On initial cranking there is a nice big bright spark, but 1 to 2 seconds later its a weak spark - could be the problem, but its a real puzzle.
Any thoughts?
