I recently just bought a F150 stx and notice the first night flickering dash and headlights. After taking it back they updated the PCM. When i pick up the truck i wanted to change the stock radio out and put in a pioneer head unit and new door speakers. Will this mess with PCM again. I dont want anymore electrical problems but i also would like a new headunit. Any feed back would be much appreciated.

 

Nope, it should be fine. Just get yourself one of those wiring harness adapters to make it easier.

 

Thanks man. Big relief to hear that. I already have the harness and mounting kit so im good to go. Thanks again
