I picked up a Pioneer AVIC-F700BT, it was a deal so it was missing the preamp wire harness. There are times when you find a cheap car stereo missing a few accessories (thats as much as I'll say about that). When you do, you'll need a wire harness. I thought it would be helpful for certain people to write a how-to on making your own.

Step 1: Starting out

This is the port that we need a harness for. It has 12 pins and handles the preamp outputs of the stereo for connection to an external amplifier. The harness for it would come in the box if this unit was bought new.

The first thing you need to do is find the pin-out diagram to tell which pin handles what function. These things are available all over google for whatever port you might find.

What else do you need: Soldering iron, glue gun, continuity tester, shrink wire, port connector, female a/v jacks
Hello I have a Panasonic cq 100 800u I believe I need help finding a graph like you have to know the meaning of each color wiring thank you
I'm looking for a way to find configuration pins for the power plug, any thoughts?
 Won't hot glue melt when the dashboard gets hot?
Maybe, its mostly for durability during the install, after its in the dash its not like the wires will flex and move around much. So even if the hot glue gets a little mushy in the heat, i dont think it would be a big deal.
i wish i read this befor i spent almost an entire day at the junkyard looking for one that would fit my stereo
good idea i buy head units alot cuz i have anger issues, and i never thought of this, save me 25 to 50 everytime i need a new wire harness, i would jis order them now i can jis make um thanks-jman
