diagram time!
Sounds like the 97 diagram should work for an 86... what
year is the decomp controler from?
just checked the ignitor on my 97:
1: Black/Yellow tracer -> ignition coil;
2: Black, no tracer -> starter relay
3: no wire
4: no wire
5: Orange/White tracer -> ignition coil & kill/start switch = + 12V
6: Green, no tracer -> magneto pickup coil
7: Orange, no tracer -> magneto pickup coil
8: Black/White tracer -> ground
