I would ck the 2 wire plug at the back of the radio for power. Could look like either, 79 radio plug on left, earlier radio plug on right. Call and ask gene as far as radios on hand.
79 radio power plug.
Maybe a local radio shop can help, but it not."The OEM radio was powered by a GREEN 2-terminal pigtail. YELLOW with a BLACK stripe is switched power, BLUE with RED stripe is dash illumination. Do not mistake the BLUE with RED stripe wire for ground. The OEM radio grounded through its mounting chassis. The speakers were connected over a separate pigtail.
Looked behind the glove box and find a connection the goes off the green and yellow. GREEN with YELLOW stripe wiring is hot-at-all-times power for the courtesy lamp circuit. Use that. There is a black 3-connector pigtail behind the glove box (which also goes on to power the cigarette lighter).
It's not the stock radio wire because the stock radio didn't need hot-at-all-times power (EXCEPT the factory digital AM radio for clock memory).
solid black—power
blue with red stripe--dial light
black with gray dashes—ground
orange with green dashes--right speaker
white with green dashes--left speaker
Assuming an AM/FM stereo and stock wiring harness'. Purple is ground, right speaker is white and left speaker is orange.
A blast from the past, "For OEM radio help, the guy to use is in Scottsbluff Nebraska. His name is Gene Cochran, and he works out of his house. He's a crusty old codger, but does some tremendous work. While he had the radio apart, he updated some of the internals and cleaned the heck out of everything. My total bill was $25! His number is 308 632-2520 (I checked with him at the time I collected my stereo, and he was OK with giving his number out) He also lined me out on the manner in which the old radios were wired (mine at least). The speakers are in series meaning positive from radio to positive on speaker #1, negative from that speaker goes to positive on speaker #2. Negative from Speaker #2 goes to Negative on stereo. Now the stock stereo rocks as loud as the little 5 1/2 speakers can handle!!!
While it's there you might see if he'll wire in an aux input jack. I had it done with mine, and it allows me to run my I-pod through it. Basically, when the I-pod is connected it becomes the antenna source. Cost in parts was under $5. I set mine on a 12" extension so I could just drill a small hole in the dash by the ashtray, which I'm turning into a covert charging / storage station for my phone and I-pod. won't cost much more."
Also I don't know if I mentioned it but my radio is a AM only not a Am FM didn't unforunetely come with a FM? I might someday switch it out for a original AM FM if I can find one that works.

79 radio power plug.
Okay thanks yes my truck is a 75 f250 which has the green style plug which of the 2 wire coming out of the plug is the hot for the radio and can I ground my test like on to that wire to see if I have power coming through?
Radio
Yes and as far as I know BOTH those wires are HOT. One is keyed 12v and one is constant 12V for the radio station memory. And the radio gets its ground when installed/mounted.

Okay so it will be okay if I ground my test light and touch each ones and they should light up if they are getting power correct?
Yes, that should correct. I believe one of them might not get a full 12V.
Okay I talked to Gene today and he is checking to see if he has a original AM FM in stock and said he is surprised my radio doesn't work because most of the AM ones like I have work so I am taking it out tomorrow and test it again and if it still doesn't work he said he can work on it thanks again for reccomending his number to me!
