Haven't had this happen personally (2020 AT4) but I seem to recall a review either on this forum or on the Pedal Commander website of a T1XX revving on startup. Never saw a solution posted...

Agree. Tight fit. Only tip is, if you are using LEDs that require the correct polarity, check that the bulbs light up before screwing the bulb holder back into the frame...

Pics as promised:

Sweet ride! Which Air bag kit did you use?

I installed a BAK Revolver X4 yesterday using the J-Nuts and bolts from Amazon Spec'd by TomCarbonPro using a similar method to that posted by hammick. I would like to thank them for their posts which made my job much easier. Here is how I did it: 1. Drilled 1/4" holes in the plastic bed-rail cap at the location of the 6 underlying round holes (aft hole is prethreaded). 2. Marked the fore-aft location of each hole on the bottom edge of the bed-rail cap with a white marker. 3. Set the cover side-rail on the bed rail in the location spec'd by BAK (all the way forward) and marked the fore-aft location of each of the 6 holes with a white marker on the bottom edge of the side-rail. 4. Measured the up-down location of the holes with respect to the bottom edge of the rail cap (which extends below the bottom edge of the side-rail by 4mm). Center of each hole is 12mm up from the bottom edge of the plastic bed-rail cap, so the center of each hole is therefore 8mm up from the bottom edge of the side-rail. 5. Drilled 6 1/4" holes in each of the cover side-rails 8mm up from the bottom edge. 6. Installed 10 J-nuts in the 5 forward holes in each side of the bed, the aft hole on each side is prethreaded. 7. Set the side-rails on the bed rails and installed the 6mm bolts, loosely at first until all were installed then tightened them all. Each bolt also has its own washer. The front bolt was the hardest to get to, so (on the second side) I installed this bolt first. 8. Rolled the cover onto the side-rails, adjusted fore and aft til aligned, bolted cover into place. Notes: 1. BAK sends out adhesive pads to shim the side-rail for different contour bed rails. I considered the CarbonPro bed-rails as "straight" and didn't use these shims. 2. The clamp on the left side-rail didn't close tightly against the "teeth" that hold the cover closed/locked. I used a small piece of one of the adhesive shims to shim up the button that pushes the clamp down by the latch so the clamp rotates further closed. This worked well but I'll manufacture a more rigid/permanent solution when I get a chance. 3. I'll post photos later today or tomorrow. I should also note that I am a new member, first-time poster, and recent bedcover forum lurker. I recently moved up from a '16 Yukon XL to a '20 AT4 CarbonPro and couldn't be happier.
