I also have a ignition wiring issue on a truck I just bought.
To keep things consolidated, I posted here rather than starting a new thread.
I think the ignition switch has something wrong for the previous owner to have it wired this way.
If I take something metal and arc the center post with the post to the right (purple wire), the engine will crank and start.
Pictures help me:
Here is the wiring at the ignition switch:
It appears I need a Purple wire to the center post, and a couple browns to the ACC Post.
But I'm thinking the previous owner left them unconnected because of some electrical issue.
Where should I order a new ignition switch from?
The one the truck has now is just hanging there, so I'll also need the OEM nut that connects the ignition switch to the dash panel.
