Radio wiring.

Kinda confused on these plugs for my radio harness.
This dash harness was supposed to be from a 86 442 so maybe it had a different radio option than all my other G’s
Also seems to be missing some of the speaker wires.

You're missing the blue plug that's for the rear speakers which is a stand alone harness. Other than that it looks like you have everything else. Black 4 cavity with 3 wires for power & back light, white for the front speakers, black 2 cavity for the clock memory & back light dimming. Not sure what Olds used those other plugs for.

I cut the clock plug out. Now that you mention the rear being a separate harness I remember tucking the wires in the black channel that’s mounted on the firewall. The PO cut off the plug.
I’ll check the service manual I have to see if I can find anything on the other plugs.
Unfortunately when I purchased it I was only able to find a digital version and it’s pain to navigate.
