Pioneer - Metra - Orange wire - Installation help please May 13, 2016The metra harness I bought (70-1761) that was packaged in 2012 doesn't have orange/black like most have reported about theirs. It DOES have a mostly orange wire with a faint and thin white stripe on each side. Metra 70-1761 Wiring Question for 2002 Tacoma Pre-Runner Apr 06, 2013The other wire I have on the Metra Harness is a Orange/Black wire which is NOT specified in the Metra wiring list. I wish I knew what that one was for! Instead of the Orange/Black wire, it lists an Orange wire as the "Illumination" wire, but I don't have a solid orange wire on the Metra harness.
