Myster capacitor? under dash, please identify

Hello, I was looking under the dash at the headlight switch and noticed this, what I assume is a capacitor, mounted onto the parking brake braket, sharing one of the bolts. It wasn't hooked up to anything so I pulled it off to take a couple pictures. My question is, what is it? and Should I put it back? I couldn't find any mention in the shop manual, have yet to look in the parts catalog. Thanks for your time.


Best I can read it says "CORNELL-DUBILIER MC9C00" "202043 .5MFD100VDC"

Yes, that would be a .5 microfarad capacitor. If your truck has (had) a radio, it might have been to reduce the spark noise in that. But I really don't know.

Noise filter for a radio would be my guess too. A long way to the radio though. Do you have an antennae and if yes what side is it on?

Not a Ford item. Usually radio noise supression capacitors are attached to electrical components such as generators, coils and voltage regulators. Last time I checked, the E-Brake isn’t electric. I would file it under “un-necessary”.

When I was swapping the horn relay I noticed another capacitor, same type hooked up, I think to this box with that connector. Not sure what either are, would appreciate the help. I don't have an antenna but there was a hole in the roof and a few screws suggesting something was mounted up there before, not that I'm sure that's related at all.

Thanks for your time.

Capacitor on left, relay? on right

Not sure if you have a wiring diagram but this may help if not.
