I am trying to figure out what the small capacitor does that is mouned to the fuse block on my 74 GTV. Its behind fuse #11 & 12 and it has a thin blue wire leaving it, mine is cut and I am wondering wherte it use to go. It does not seem to show it on the wiring diagram. Thanks for your help.

The only caps I'm aware of, other than the one in the dizzy, were mounted on the alternator and/or ignition coil to suppress RFI. And even then they were not installed in all years/models. It could be, since it's by the small fusebox, that it was installed to suppress fuel pump RFI. But that would be the first I've heard of it. Perhaps it was installed by a previous owner for some sort of sound system or something. Does it look like a factory install?
In any case, if everything electric in the car works, and since the wires been cut, I'd toss it in the bin.

It looks to be factory, its about the size of a condensor that goes in a distributor, it mounts by being sandwiched between the small fuse panel and the bracket it mounts to. The cap/condensor mounting tab is the exact same size of the small fuse block and is sloted to accept the allen bolt that holds it. Sorry for the pic being kinda unclear. I guess I will leave it be for now.

I think it is/was there to supress interference on the radio. Quite common in the dark days of the 70s.
