Vehicle Fitment

This product will fit the following Mustang years:

Rated 5 out of 5 by from great video but easier install suggestion I was hooking up power for my radio, and wanted to attach to the IS. I got the core out, but the bezel and IS were impossible to get out. I was a about to give up trying to get the switch out--I could not get my fat hand back there to apply enough push and twist. Then I thought I 'd try removing the instrument bezel. And there it sat, ready to be plucked out with a flip of the wrist. (Of course, learning how to take off the bezel three months ago is another story.) Anyway, much easier to remove and to install by going from above.

Rated 5 out of 5 by from Worked Perfectly. Bought this for my 66' Mustang after the original separated and became a hazard (due to not starting/not staying started/or continuing to start after ignition). Install went without a hitch and my pony is back on the road.

Rated 5 out of 5 by from She fired right up! I bought this ignition switch for my 1966 mustang as the ignition switch in my mustang was turning freely. I watched the installation video to get a better understanding of the job ahead of me. The video did state it would take roughly an hour or so to install and he was right. The only thing that I would add to the video it that the slots on the ignition switch aren't identical to each other and that the ignition switch needed to be oriented correctly before you place it behind the panel. Other than that lessons learned, installation went well and the ignition switch resolved my ignition switch issue. I got the new ignition switch wired, installed and mounted and she fired right up without any a repeat issue.

Rated 5 out of 5 by from New switch fixed new problems After updating almost everything on my 66 I had different issues with some of the new components I had installed(some major). All tracked back to the switch. It was time to swap out the 50 year old original piece.

Rated 4 out of 5 by from Ignition switch for '65 Comet Caliente This arrived quick and went in smoothly. Functions fine. It is shown with a nut that was missing on mine. The old switch is threaded SAE, new switch wasn't so I couldn't reuse the nut. I scrounged around and found one on hand.

Rated 5 out of 5 by from Perfect replacement Old switch would occasionally just shut off and poor contacts. What do you expect after 50 years. This guy brought it back to new life. Easy install.

Rated 1 out of 5 by from ignition switch assembly Switch came without a nut for the threaded terminal. I have tried every American @ metic nut I can find and nothing fits. This is a china only thread

I believe that the new switch I ordered is defective because I have power to the ground stud at the rear of the switch.

is there any way to remove the old one without turning to key to the acc position my key will not go to acc and i have not been able to remove the cylinder or the switch assembly?

Asked by: Noah
At that point there is no easy way to remove it. You would have to drill the lock cylinder out or what ever method you feel will work.

New switch not fitting inside ignition

Asked by: Carolbu
The ignition switch tumbler has to be in the correct position to install into the switch. The tumbler has to be in the accessory position so a small pin or a paper clip can be inserted in the hole to depress a pin, once the pin is depressed the tumbler can be turned counter clockwise one more position, the tumbler can now be inserted into the switch.

I no longer have the key for my 1965 mustang. I bought the Ignition switch cylinder but understand I can't get the old one out without the key. If I buy a new ignition switch assembly, will I be able to remove the old one without the key?

Asked by: TTT1
No, the tumbler needs to be removed from the switch.

Asked by: timbo1958
Yes, this doesn't replace the lock cylinder. They are two different pieces.

My 1965 Mustang ignition is bad.  I cannot turn the engine off.  The motor continues to run.  Do I need the switch assembly or the switch insert where the key turn on and off

Asked by: Big Man
You would have to remove the tumbler from the switch to see which one is bad, most likely it is the switch.

hello, i replaced my ignition switch from my '65 mustang and now i cant get the key out if the ignition. What did i do wrong? Can you help?

Asked by: joe 65
My guess is that the key didn't stay aligned in the lock cylinder throughout the process. Try reinstalling the lock cylinder.
