Title: coil pack wiring
Post by: Paradox1 on October 06, 2016, 12:21:53 pm

Does anybody have  awiring diagram for our coilpack look.
Or can anybody tell me what each wire on each coil pack does?

There must be a pin-out diagram on the net somewhere, but your 4 wires usually consist of:

A thick wire with a red tracer = +12V
A thick brown wire = Engine or chassis ground.
A thick brown wire with a tracer colour = Engine or chassis ground.
A thin wire = ECU signal.

Do a continuity check with a multimeter on the brown wires to the battery and the engine.  If you get beeps, then 100% the red wire is 12V and the thin one is ECU.
