First one is, I noticed that the control wire for the cd changer (clarion, I think) in my 95 4.0 SE seems to be the same as the one from my 94 RR county (pioneer), does this mean I could interchange them? Cause the Pioneer one never skipped, even when off-road and the other one Skips way too much. Second question is, does anyone know if the audio leads that goto the sub are High level or low level? I want to tap into them and run them to my own sub box/amp and not sure if I can run them into the low level inputs or if I need to go through a high to low level converter then to my amp etc.....
