ummm perhaps? lol
I was under the impression I needed the Metra 70-1761 harness lots of people on here use. However, if that's already on there, then I though I'd splice wires to the new unit.
All aftermarket decks use the same connector
You sure about that? I don't think you're correct.
The plug in the deck? Yes they are universal unless you are talking about something I never seen....they also use the same color wiring across the board. These plug and play harnesses are the same on deck side but different on the car wiring side.
You are absolutely wrong. The wire colors are the same, but the plugs are different by manufacturer of the HU.
Here are 24 different aftermarket HU plugs that Metra sells:
