Spark plug wires.???

[Luis325]

Are spark plug wires different in a 1986 325e than in a 1987 325i??

Im doing a 327i swap and i got the 325i 1987 wiring harness? Should it be different?

Thanks

325i has an impulse sensor on the #6 spark plug wire that the ECU uses to synch the injector firing order to the crank.

Ok so im missing the 325i sparkplug wires....Shit....
I was supposed to fire up my car today..... Not anymore...
Does that come alone of is it a complete wiring?

Where can i get it?

The engine will run without the Cylinder ID signal. The fuel mileage will be worse and the engine will run a bit on the rich side.
