Quick question on wiring a headunit

[Justin327]

Hello Guys,

I've done some searches on installing a new head unit and from what I've gathered the yellow and red wires on the harness vs the deck are reversed.

So am I correct in assuming that when I'm spliceing together the decks wiring harness to the Metra adapter harness I just connect yellow to red and vice versa? and then plug in the adapter into the harness that came out of my Becker unit?

Just want to make sure I didn't have a brain fart and misunderstand what I was reading. If it matter's it's a 2001 S, with door speakers, nothing crazy.

Thanks!
