No money to afford a wiring harness - premium system with amps, so the harness is $36. HU is from my old car.
I'm confused as how to wire this. On the factory HU, are the outputs (I'm looking at a diagram of it) the pre-outs to the factory amplifiers? Or are those completely separate? On this, they only have one of the plugs on the HU - there's a second one in it in actuality, with a few more wires.
This is the diagram so far as I know. If I want to hook up my HU, how should I go about doing this? And before it's mentioned - connections will be secured, I'll make sure of that.
'Tis an Infiniti G20, 1996, for anyone who would have firsthand knowledge.
