Wiring issue

[Tate Baker]

So I have a 1988 gmc 1500 regular cab and I had rear speakers but no wiring harness or hook ups, I grabbed a harness from a parts pickup but I’m unsure of where to hook it up to or if I should try to find a way to splice it into the front speaker wiring.

Should have a plug for the rear on the radio. Is it aftermarket or factory radio?

It’s an aftermarket radio but I’m trying to hook up wiring to the speakers themselves, the previous owner stripped the speakers and wiring from it.

I have an 88 k1500 Chevy as well as a 93 k2500 Chevy same wiring. I've got the rear speakers and pulled all of the wiring. If you only want the stock speakers I can send you just the wireing harness, or harness and speakers, even radio and cassette deck. If you will pay just shipping you can have it all.

   Also if you Google the brand of radio that was installed in your truck you should be able to find the proper wiring diagram.
