So my 3rd brake light went a while ago and its about time i replace it. My tail lights are all l.e.ds and they have the resistors from rotaryfx. The original owner had them set up and everything. I was planning on getting the led third brake light set up off ebay and im wondering if i would need another resistor for it, i do not want to get the abs/tc light on again. Also after i changed my alt, everytime i turn on my head lights, i get the high beam light on my dash but it isnt on. My fog lights are out and when i try to flash the high beams nothing happens. help me out with these pleaseee! oh dont tell me to clean my grounds cause ive already done that
