Im not 100 percent sure if it is the ignition switch but im hoping it is (especially now). I was getting a intermittent spark, but most of the time no spark, and sometimes one little spark when turning the key back to run. The car will start right up if I jump a wire from the positive battery to the positive side of the coil. I think the photo makes the cam appear broken. Here is a better picture. I have a new one also. I will try to push the tabs in to remove the wires out of old plug. I did notice that they go in one direction. So just pulling them will make them dig right in. Thank you a million Nacho and all others.

Ahh yes! I see it now. Hope this one works. It looks like more work than changing out the entire harness.

Can't tell if that one is the correct one. Some resto shops advertises to earlier models

You can get the old wires out of the connector by using a home-made tool. I use a piece of thin wall tubing...a chunk of 1/4" brake line might work. Carefully slide it into the business end of the connector to push the teeth away from the plastic and slide out the wire with the tool. Once clear, remove the tool from the wire.
Looking at the pic of the back side of your steering wheel, it looks like the contact wheel has worn a groove into the contact ring. When you turn the wheel, it moves the contact against the cancel tab, thus grounding out the circuit and honking.

Thanks, The contact ring is not grooved. Its just a shiny area .
Is that nub sticking up the cancel tab? Notice the black stuff on it. I realized its (rubberized) material. Possibly to prevent the contact wheel from grounding on it? A previous owners attempt to fix it?
Should I clean it off?

Not my steering wheel. For ease of reference, I just swiped that picture off eBay

OK, I have a new theory. One or more of your switches is constantly contacting (this is relatively common) and the electrical conductivity between the contact wheel and ring is iffy, so when you turn the steering wheel, it improves the electrical flow, thus completing the circuit. Do you have another wheel to try? Maybe someone here on the board has an extra switch assembly for cheap?

As you know from the thread that im changing the ignition switch harness. I recently decided to order a whole new turn signal harness as well. Since the turn signal cam is broken, its only $43 shipped and all the work it took to get to this point. Only the new turn signal harness doesn't include a new contact wheel. Guess il have to see what happens.
Does aanyone know if the nub sticking up on the back of the steering wheel is supposed to have a rubberized/insulated coating like in my picture above?
Im thinking someone was trying to solve the horn issue before me.
