Need help with my wiring harness for my pioneer, can't figure out which wires are for what?! Can't figure out which ones are for my front speakers and my back speakers. Tabs on the wires were missing when I got it. Unfortunately it didn't come with any schematics in the bag. I have a pioneer 7800 head unit, installing 6 1/2 Diamond speakers in my front doors. And Infinity 4x6's Kappas in the back, along with my sub box with Infinity 2 10 inch subs 10.1d's, any help would be great. Just want to finish this I just can't figure out which wires go for what. The wiring harness for my pioneer didn't have any info.
