    WARNING: FCA will void your warranty if you do this.

    I agree. I had this same exact setup in my f150 for 2 years no issues. I'm going to contact the radar manufacturer to get the actual amperage of the device, but it's probably next to nothing. I guess it'll be up to the arbitrators to sort this out... and the state AG office.

    2021 Ram 1500 Big Horn Fuse Diagram and the BCM

    Thanks for the quick response. The F66 fuse works as its supposed to, turns on on run and off after the delay or door open. I don't think there's anything wrong with F66 or anything cause by the radar detector but the dealer is trying to void warranty solely due to the radar detector installation.

    2021 Ram 1500 Big Horn Fuse Diagram and the BCM

    I bought my '21 Ram 1500 a few weeks ago. It had a battery drain and has been at the dealers for 10 days now and they don't know what's wrong. They think it has something to do with the body control module (BCM). Anyways, I had a radar detector I installed the day I got it using a fuse jumper...
