2006 kia optima lx etacs bad?
My girlfriend had me install a new radio, but some how i was given a wiring harness for a new model withing the 2006 year range. I hooked up the radio and it smoked. I pulled the radio off and put the old one back in and it worked until i got the correct wiring harness. I put in the new radio with the correct wiring harness. The new radio worked but then stopped after about a minute. the old radio doesnt work anymore. When i connect either radio now the trunk open light comes on and stays on. when the key is on Acc or if the car is running when i hit the power locks to lock it locks then unlocks right off the bat. could this incorrect wiring harness cause problems with the etacs and maybe burned something out in it? I checked the power coming into the wiring harness for the radio and it still has power to the correct wires.
If anyone has some advice it would be awesome so i can get this issue fix so my GF can have a radio again and not have the power locks issue and to get that trunk light from staying on. Thank you very much
