Many late model trucks have battery connections as shown in figure 8. The ground
cable from the battery may be connected directly to the engine block with only a light
braided ground strap connecting the block to the chassis. Where this is the case, the
factory installed cable does not provide an adequate ground circuit for operating bat-
tery powered liftgates. We recommend that the cables labeled with an “X” be not less
than #2 gauge cable as supplied in the installation kit. Also because of the high cur-
rent draw (approximately 200A) we recommend that the alternator be a heavy duty
type and the battery must have a 150 AMP minimum reserve capacity.
