Today on our 1999 Chevy Silverado well be adding the Hopkins Adapter Four Pole to Seven
Pole and Four Pole, part number 37185. This vehicle was previously equipped with a four
pole that was direct wired to the manufacturers harness. Its already been removed so we can
go ahead and strip back the brown, green and yellow wires that run directly from the manufacturers
tow package. Then well add the butt connectors to each end. With that done were ready to
go ahead and add the bracket to the seven and four pole. Well use the hardware provided
to secure the bracket to the seven and four pole.
With that done were ready to go ahead and mount it to the vehicle. Well mount it directly
to the bumper here using several self-tapping screws. With that done were ready to go ahead
and start wiring it up. Well go ahead and clip off the excess from the purple wire,
which is used to hook up reverse lights to the trailer. We wont need that for this application
so were just going
to cut off the excess.
