1987 GMC S15 Electrical Problem
When I turn on my lights the blinker lights on the dash stay lit and all my gages stop working. It all started when I tried to install an aftermarket radio with the wiring harness from the radio and the Metra 70-1677-1. I wired it all up and it worked great and then I unplugged the harnesses to put on the radio trim. I plugged it all back in and it went bonkers. Now the radio will not come on and the lights are messed up. I unplugged the radio and all the after market wiring harnesses and left just the stock wiring that was in the truck originally and the lights are still messed up. I have checked all fuses and can't figure out what is wrong. Please help!!!
