XRT™ Body Modification
Using a tapered body reamer, carefully cut a
small 8mm hole in the truck body. The hole
needs to be large enough for the rear light
bar harness connectors to pass through (note
the hole diameter measurements on the body
reamer).
Install the high-voltage power amplifier on the truck chassis. Ensure that
the connectors on the amplifier face the front of the vehicle. Secure with
the 3x12mm button-head screws.

the roof line and rear window as shown. Using a tapered body reamer,
carefully cut the holes in the truck body for the screw bosses on the
rear LED light bar mount and the rear light bar connectors (note the
hole diameters indicated on the templates and the corresponding diameter
measurements on the body reamer).

extremely sharp and can cause severe injury, deep cuts, and/or punctures.
CAUTION: RISK OF DAMAGE TO
ELECTRONICS!
To prevent damage to the electronic
speed control (ESC) and/or the high-voltage power amplifier, ensure the
battery is disconnected before plugging the amplifier into the ESC.
