Original wiring harness.
A buddy of mine clipped the original wiring harness for the stock radio, he rewired it but when he plugs in the stock radio my trailblazer wont start. when its disconnect it starts. What would cause that to happen?
there is a wiring problem. you will have to go back through the wiring that he cut and see where he messed up reataching the wires there is a positive to a ground throguh the radio some where. this is where I would start first sense this is the thing that has been changed
In addition, once you get the wires hooked back up to the original plug for the stereo, see if you can buy a jumper harness. This is a small wiring harness, maybe a foot long, that plugs into the dash wiring harness on one end and then into your new stereo on the other end. This is much easier and safer than cutting and splicing. Remember to disconnect the negative (-) battery cable before starting the repair as well. HTH. -Jim
