I purchased a 05 grand am with an after market hu. Already installed. I was trying to upgrade the hu. When I got to the wiring there was all sorts of wires messed up.
can someone please help i have hooked up probably 30 far audio setups and never been stumped like this please help

You're going to need to do better than this. Read what you wrote.

never seen this

the wire in my hand was spliced into that pink wire behind it

And I have tried 2 different wire harnesses with 2 different hu. And I got nothing from either that'* when I opened her up

Well. Not knowing what model hu you are working with and no wiring diagrams I think I'm done here. I don't know how to help you.

I"m really curious about the relay he'* got. Why on earth is there a relay for the HU?

You need schematics for the HU and your car.

I'm not sure he'* working on the HU.

Ok so that relay doesn't go to the hu but its wired up funny.
the hu I want in is a kenwood do I need an expensive wiring harness

I think whoever did the current hu grabbed a power or ground from that relay but without a diagram we have no way of knowing. Not feasible to reverse engineer it.
