  1. I have a 2005 chevy colorado single cab and I’ve hooked a new cd player up in it. But I’ve come across two purple wires amidst the harness that a dont know what they are. They seem to be linked to the tweeters in the doors but do not have markings indicating positive or negative , in fact they are the same color purple. whenever i do hook them into a line from the cd player one side of the door speakers gets louder than the other. Does anyone have any idea what they are and how i should go about hooking them up? Also the tweeters in the doors don’t work at all so there has to be a link between the two. anyone? thanks

  2. what are the purple and the purple black wires in the radio harness. on an other site i found it calls it a 1807 Class 2 Serial Data what is that? could that be the accessory switched 12+ volt im looking for? anyone?

  3. i am looking for the inside relay & fuse panel, of my 2004 chevy colorado. it states, i should remove the seat belt fuse, if i work around the steering wheel. i looked real good with a BRIGHT trouble lite. and found no panel on the left under dash. why would the manual say take it out? if there was a panel?

  4. on the factory radio in a 2004 chevy colorado does it have aux line in where you can plug something into it to use the speakers in the truck for sound?
