Trick to removing ignition switch?
I replaced the wiring harness in my 77 F100 with the harness from a 75. Everything seems to line up accept the ignition switch plug. I would like to exchange the switch to keep the wiring harness in one piece. I think I can keep the same keys by exchanging the core. What is the trick to remove the switch assembly? Is there something about a wire inserted in to the face of the switch to pull the tumbler out? I haven't really looked at it close yet. How does the entire switch come out?
Thanks,
Shane

I dont remeber which way it goes as it's been a VARY long time. But you either rotate the key to acc(left)and insert a paper clip in the hole and you'll feel a spring loaded "button" push in and keep turning in the same direction and it should come right out. Dont forget to disconnect your battery first. Good Luck

That is what you need to do to remove the lockset from the switch. To remove the entire switch from the dash you need to simply remove the screw on retaining ring on the outside and pull it out through the back of the dash. Then, if you want to change lock cylnders to retain your orginal key you would go through the process above.

Thank you, just what I was asking. At first glance, I didn't see how the assembly came out from the dash. I will change tumblers and keys as well if possible. I see in a parts magazine that there is a different ignition switch from 75 to 77 trucks listed. Everything else seemed to connect back up ok. The original harness sure was a mess.

Not uncommon at all in these old girls, if I remember correctly though there are only 2 different switch assemblies used with the difference being the size and configuration of the plug on the back. It seems to me that one had roughly 5 wires, and the other had 7? Just speculating. Anyways, welcome to the site.

You are correct. I think I counted 6 wires on one plug and 7 on the other. Other odd modifications were, all the seatbelts had been taken out, wiring was never completed to where more than a few lights worked, and the dash guages wern't hooked up. The speedometer gauge was glued to the back of the houseing. No 2nd housing or circuit board existed. Front disc brakes were beyond shot, and the 6 cyl had been replaced by a 302. Also someone tried to mount 6x9 speakers where the shoulder belts bolted to. It ran good and other than a few small spots, the body is rust free and solid. I had a 73, Orange, F100, 302, 3 speed truck in high school and now I have a 77 truck exactly the same again. Should be back on the road in a week or two. There is alot of good information on this site.
