1969 Mustang AM radio ground

[Nigel]

This may be a silly question but how do you ground the AM radio? It has 3 wires coming from it. 1 power and 2 speaker. The light w/wire and the antenna plug.

It grounds through the radio chassis.

My 8 track version has a ground wire that goes to the case, attached with a screw. Can't remember where the other end ofthe wire goes, somewhere in the harness.....you could probably just ground it to the dash.

Thanks for the info. I see a screw a something that looks like 2 solder point. I think that may be what you're talking about.
