Ok, I have 2 harnesses behind the radio. One has 10 or 11 wires and the other has 6. The one with 10 or so has all the speaker wires I know and the ground. I have a pigtail for that. Now, I can't find a pigtail for the 6 wire plug and I have no idea which is the power/battery and the power/ignition. I can't find anything with just a 6 wire plug. Everything I come across has at least 8 wires. Can someone tell me how to wire this?? PLEASE!

hey i went to ford cause i had the same issue. i have a 1998 F150.
the guy there said that is is really hard to find them because they, well, don't usually make wiring harnesses for the 1998 trucks and SUVs. so i took my car to a professional who just cut of the old plugs and just soldered(i have no idea how to spell that) the wires that came with my after market head unit straight to the pre-exissting wires. it didnt cost that much. and it saved a lot of frustration and time
