Black, white and blue connectors. Delco makes a kit. It’s cheap, comes with crimp on ends that go in the plugs. Your GM manual should show the hook up. It’s usually stamped in the case what wire is what.

Those on eBay may not be the correct ones. If your radio looks like my radio in the top pic, then the connectors look like the ones in the other pics. Here's a link to ones that will work. It shows 4 connectors in the listing, but only 3 are needed...the ones with 4 contacts each. https://www.ebay.com/itm/DELCO-GM-GM...UAAOSwNlleDlwP

the connector i linked to will work for the style radio you pictured as well as many other years. i have the same radio as that in my 78 as well as the digital tuner type for my 81 & use the connector i showed, it works & installs perfectly.

the new reprod 1 piece connector simply combines all 3 of the individual ones you show into one connector. look closely at the one in my link, it has the same 4 contacts per section as the individual ones you showed & lists what each color wire is for. just a easier/cheaper way to repro them.

Okay great. I see what you mean. Thanks for pointing that out. Not looking like the originals, I didn't even notice they combined them into one plug.

yep, i was curious about that too when i saw these 5+ years ago & asked the seller who confirmed they work for all these style radios. from 75 or 76 to the early 90's GM used the same connector on their radios.

Good to know. Do you know what the extra connector with 2 contacts is for?

not exactly sure but i think they are for later models that have an extra feature the older radios dont have, like maybe the led light fader? just a guess.

it should be stamped on the radio.... or look at the link i sent for a new plug, it explains what each color wire does & where it goes.

Probably so. Glad I'm not the only one that didn't know what it's for .

You're right, I have seen pink for that too.

Here’s the Delco kit. They were $10.
