Ok, now I'm with ya. And yes, Jack often helps.
I used the same type of in-motion relay with this harness as well.
Yeah - post some pics if you can.
As far as the speaker wires, I didn't connect any of them because I am not using the stock amp at all. But if I were to, I'd connect them wire-for-wire as they should be - just ignore those strange instructions about the rear speakers when amped, etc.
Couple things... Only use one of the two yellow wires from the PAC for the constant 12v. If you are using both yellows it could cause interference. However, you can use both black wires from the PAC to ground the HU, and also ground the relay all together.
For the amp turn on lead, you want to connect the HU's blue/white to the PAC's blue/white, and the bypass's blue.
For the parking brake, you want to connect the HU's light green to the PAC's red/white, and the bypass's green.
For the reverse (if you are using that function), you connect the HU's violet/white to the PAC's green.
I think that should be the only tricky ones as I am looking at the manual for your HU. Everything else should match up color for color I believe.
Hope this helps.
