Poke it with a tester and have someone turn key on and off. Don't skin wire back - problems after!

Ignition switch might be a blue or a black and white wire too from what I researched.

I didn't read the whole thread.

Ignition wire is BLUE as shown in this pictures. I have a white pigtail spliced to it.

Maybe this is helpful to you.

Sorry, meant to agree with you on that.

You can verify the wiring with the diagrams in the FSM. Haynes was not helpful to me on this one.

Dang! Theat's the photo I was looking for! I could not remember who posted it and I got colors mixed up. Done too much wiring lately to keep it all straight. Oldtimers thing.
