GM 8 track player install question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Tuff Gong · 08-14-2016, 06:20 PM

anyone out there ever installed one of these? I would like to test my unit but have not idea where to start.

Tuff Gong · 08-14-2016, 06:53 PM

Some of the wiring has been altered over the years and it is not really making sense to me what goes where. It appears the radio speaker attaches directly to the 8 track player and speakers look straight forward (see pics).

I'm having trouble with the power wire and additional stuff on the harness. Here are the pics of those wires.

Any chance you can confirm the manual covers installation? Or perhaps post a couple pics?

Have you looked inside the covers on the radio/8-track player?
Sometimes there is a hook-up/color code diagram inside.
Mike.

Here is a hook up instructions sheet for wire harness, and where and how to mount speakers.
Sorry this is the only pic I have of each saved.
I have not installed my own tape unit in my truck yet

Have a working pioneer 8 track in mine but had a shop install after I cleaned it and put in a new belt. dont forget the correct ohm speaker...

Tuff Gong · 08-16-2016, 09:27 PM

Thank you for the responses. I'll take a look at the diagram. Hopefully it gets me to where I need to be.

Tuff Gong · 08-17-2016, 11:03 AM

It would really help if I could see an example of an uncut wiring setup. Based on the diagram I think my speaker wire off the 8 track is not correct. I also have no idea what the wire labeled as (?) connects to. I believe #4 is the main power supply. Anyone else have any thoughts? Thanks.

**burb71** · 08-17-2016, 01:57 PM

Here is the back of one of mine, I have two Original GM 8 track decks both have the same wires from the back.
There are three seperate wire connections from the tape deck.

Tuff Gong · 08-17-2016, 03:34 PM

One last question, hopefully! does the black wire on the 3 plug assembly connect to the speaker plug?

Tuff Gong · 08-17-2016, 03:41 PM

burb71, I really appreciate you taking the time to help me out.

**burb71** · 08-17-2016, 06:02 PM

There is a single plug lead also, (in added red box)

On the wiring diagram it says the 3 plug lead that go's from tape deck to radio,
1st lead... 14v DC
2nd lead... speaker
3rd... ground

The 3 plug lead from your center speaker plugs to the Crossover Network box.
Did I answser the question, or am I not understanding you?

Tuff Gong · 08-17-2016, 06:11 PM

That helps. I'm trying to figure out if the (? key note) in post #11 connects to the other harness your 8 track. Sorry if I am getting confused. Definitely not good with electrical

Almost 100% positive it does, just want to make sure.

Tuff Gong · 08-17-2016, 06:13 PM

I am going to use an old speaker harness and get mine back to original. As it sits, I don't have the attachment that goes to the existing radio

**burb71** · 08-17-2016, 06:45 PM

Just so you know, the single lead thats in the red box that I highlight, has 1 yellow wire

Tuff Gong · 08-17-2016, 07:15 PM

That is the power wire, correct?

**burb71** · 08-17-2016, 09:06 PM

I do think so, diagram says 14 v DC.

Tuff Gong · 08-17-2016, 11:32 PM

Thanks again for all the help. I figured that the 2 black wires that I see are ground wires and screw into the back of the unit. Can you confirm? No more questions after that. Haha

**burb71** · 08-17-2016, 11:55 PM

Im not sure, ill look at it again tomorrow
