I am installing my stock stereo into my RV and a buddy gave me his harness from his wrecked F150. It'll plug into my stereo but I need to know which wires go where.
In the square plug I have 8 wires:
In the second plug I have 15 wires:
and a little larger guage black/green
Please post a wiring diagram or such.
I appreciate all of the help.
*edit* There are two plugs that go into the head unit. After some digging I have found that the second plug (with the most wires) is the harness that includes the power, ground, accessory 12v, antennae and speakers. What is the second plug for (the first one I listed originally)
