Can the "Not used (spare)" fuse slots in the passenger compartment fuse panel be reprogrammed to power up only when the ignition is on?

 

Don't know what vehicle UR talking about. Basically the Body Module turns things on. The Uplifter relays are used to power accessories in the latest F150. Having the Dealer program it for another uplifter relay is how it is done.

 

Thanks - sorry, it's a 2013 XLT.

 

Maybe like this.

 

If U go that route get a 9 Volt to plug into the cig lighter to keep the Body Control Module memory intact if U disconnect the battery under the hood for a reason. It saves U the worry of loosing UR settings and whatever extra U have on UR truck. Like trailer brake control.


Here is a great thread to browse in.
