    I replaced both factory amplifiers and subwoofer (with bonus wire colors / wiring diagram)

    I recently replaced the relatively weak factory amplifiers and it was actually a lot easier than anticipated! All of the wires (documented below) were very straightforward and it was not difficult to integrate aftermarket amps in the stock locations. I also replaced the 4 door speakers while I...

    Instrument cluster display stuck on trailer info after towing

    I have a 2013 Exp with factory tow package and brake controller. After towing a trailer recently with a 7-pin harness and brake controller, the info display in the instrument cluster is "stuck" on the trailer readout. Nothing I do can get it off that screen.

Anyway, a couple weeks ago I noticed a new loud ticking sound and major loss of...

    Any issues swapping open diff for limited slip?

    I ordered an Eaton Detroit TrueTrac LSD for my open differential 9.75in 3.31 ratio rear end. Does anyone know if that will cause any issues, specifically with the traction control program that's expecting the diff to be open?

    Do the EL rear springs fit non-EL models?

    Does anyone know if EL rear springs would fit in my non-EL model? I'm assuming they have slightly higher weight rating due to the extra weight of the EL and would therefore help a little bit for towing/hauling. Thoughts? I have a 2013 Limited 4x4 5.4L that I recently got and am enjoying quite a...
