Vannin' Community and Forums Forums General Discussion Electronics 1987 G20 Radio install (no harness)

I’m installing a new radio in my G20, but I can’t find a radio harness. The old radio was just directly wired to the fuses and it didn’t seem right.

I found a harness not in use and then another one on the right of the steering column that are plugged in but don’t seem to do anything. Any ideas on what they are?

Also, if I don’t have a radio harness, which wires should I be tapping into for my new radio?

Thank you all!!

Allen

Update: I ended up hard wiring the new radio to the fuse block. Wasn’t as bad as I anticipated.

I still have no clue what those other harnesses are though. If anyone knows, please fill me in. Thanks!

That black one in the first and third pictures is the ODB1 diagnostics port.
I don't remember what the stuff in the other pictures is.
Sorry.
