Title: Need Help with Ignition Switch Wiring
Post by: southernfarmer23 on June 05, 2013, 12:38:15 PM

I have a 74 Chevy C20 3/4t, I need the underdash wiring for the "ignition switch" mounted on the top of the column. The wire colors I have are as followed:

Orange
Red
Brown with white stripe
Grey with white stripe
Pink
Brown
Red
Purple


I know one of the reds is hot, and the brown is for the wipers thats all I know. I'm trying to wire up a universal switch and mount it beside the headlight switch. I ran two wires from the starter also. Any help would be appreciated. Email me at southernfarmer23@aol.com put 73-87 truck wiring in subject

I have a picture but not sure how to upload it

Thanks, thats exactly what I've been looking for, The only thing mine doesn't have  is the yellow wire, and the dark green but I'm pretty sure I can figure it out now that I got the diagram to go by. I saw that post but I wasn't sure where to find that diagram at thanks again
