Troubleshooting - MTX Thunder sports MUDSYS41 Owner's Manual

Remove the bolts from the C-bracket so the top
bracket and C-bracket can be properly positioned around the roll cage.
Once the C-brackets are in the proper location for mounting, the bolts
should be retightened to a torque specification of 65-70 inch/lbs.
The unit has an integrated wiring harness that includes a power, ground, and accessory wire that are
designed to connect to the vehicle's battery providing it power. The wiring harness is 3 meters but
can be cut to fit the individual vehicle. The yellow wire is designed to be connected to the positive
(+) terminal on the vehicle's battery using one of the included ring terminals. The included 15A fuse
and fuse holder should be attached to the yellow wire no more than 18 inches from the battery to
protect against damage or injury if a short in the wire were to occur. The black wire is designed to
be connected to the negative (-) terminal on the vehicle's battery using the second included ring
terminal. The red accessory wire needs to be connected to the accessory switch. This ensures that
the unit powers on when the vehicle is On and powers Off when the vehicle is not being used.
