    Posted: Mar/21/2020 at 7:32pm
The AM radio that I obtained for my 68 AMX is in nice shape but I want to test it before installing it.The radio has 4 wires coming out of it , an orange, a black a green and a brown. Unfortunately there are no terminals on on the wires so I can't really determine what part of OE harness they connect to. Can anyone tell me what each wire does and what type of connector should be on each one

Thanks
Joe

Just checked my 68 TSM and no luck finding answers.  But two years ago I installed one for my brother.  If my memory is correct, the orange wire is for lighting, the black is ground, the brown is power and the green is for the speaker.  Hope this helps. Dave

black and green will be the speaker wires.
Radio is grounded through the mounting backet!

You can make the ground connection to any screw on the radio case. You'll need an antenna and a speaker of course to be able to test it. Orange is not necessary to test the radio as it simply goes to the dial light bulb.

Just to summarize so it is clear:
Brown is 12V power
Green and black are the speaker connections
Orange is the dial back light
The metal case of the radio is ground return

I tested the radio and it works fine. Now I have to install it.I can see how it fits into the radio pod and I can locate the wire connections. There is a T shaped bracket that I believe attaches to the angled mount on the bottom of the radio but where does the other end attach. Second question there is a 1/4" stud that sticks up from the center of the transmission hump is this stud used as part of the radio installation..Sorry for all the questions but I removed all of this before I put the car into storage in the eighties before digital cameras. Thirty years later I am trying to remember how things went together. Glad this site is here

The T shaped bracket ( painted black ) attaches to the bottom of the radio pod below the ash tray. The end of the the T fits over the stud on the transmission hump. A serrated nut secures the bracket/brace to the stud.
There should be a little metal bracket on the bottom of the radio that braces the bottom of the radio to the metal shielding around the ash tray. A sheet metal screw goes up through that shielding and secures the radio to the ash tray assembly. That T brace keeps everything tight and secures the radio pod from vibrating.
