I am, trying to locate a color coded wiringg diagram for 1970 442 convertible.

 

I'm not sure why you need that, If you are talking about the external or internal wiring. You need the # from the player, it may not be a 70 player, although they are all about the same. The # will look like 03B4T11 or something like that on a sticker on the back. Then you need to buy an old Sam's Auto Radio Photofact book or reprint for that #. There's a member on here who repairs them.

 

Factory or aftermarket?

 

Sorry I should have been more specific.
Service Model 93BT411
Serial Number 04789
Product Number 7307853
IT is an original Factory 8 track
Thanks

 

I think the "9" means 1969, which could still be in a 70 car. Here's a link to a "Sam's" repair schematic for sale.

Sam's were books that came out each month with radio/tape schematics, and back in the day that's what repair shops used. If you knew exactly which year/month issue it was, you could probably buy the whole issue for less. Ask the seller about the wiring colors to see if what you want is in there. Are the external wires cut?
