I tried tapping into fuse 35 under the hood to install my amber running lights last night. I wired them up and had power, but my truck went into “anti theft mode” and wouldn’t actually attempt to crank over. I reverted everything, let the negative battery terminal off for 20 mins, went for a drive then with the check engine light on. Then shut it down and turned the truck back on and the check engine light was off, everything fine now. Not sure why this happened? I’ve tapped into the fuse box under the steering wheel for my radar detector and didn’t have any issues then.
These new RAM s are fussy
am thinking of adding a voltage sensing relay and a new positive terminal from the batt and having a separate fuse box completely, straight to the battery
the volt sensing relay will drive ignition related devices
trucks are getting too complicated, would want to be offloading in this one, where all you have is a few fuses, steel wire and tie wraps.
