Trailer Brake controller install in a 2006 GMC Canyon (Chevy Colorado)
(other models may be similair)
Please
visit my general install page for overall instructions
TRAILER BRAKE CONTROLLER:
Brake contoller will have 4 wires to
connect. (I quote Tekonsha wire
colors, but many brands are the same)
Blue wire will run to the back of the
truck, and connect to the Blue (brake) terminal on the trailer plug
(drill a hole in the firewall and run the wire under the truck)
White wire is to frame ground. (find a
screw under the dash)
Red Wire taps into stop light switch (see pitctures below, Light Blue
wire at Switch, closest to middle)
Black wire is battery feed, hook to unused
fuse terminal under hood, and run through a circuit breaker for
protection, for two axle brakes 14ga wire can be used, 12 gauge wire is
better, and will run three axle trailers.
TRAILER LIGHTS:
Tail Lights will need a standard tail
light 5 wire to 4 wire converter if not already installed from the
factory. These trucks have seperate brake lights and turn signals, so
the converter is needed to convert to standard 4 wire set (brake and
turn are the same bulb)
Tap into this wire with a side tap
(scotch lock) for the brake light feed (red wire)
Below, we used standard Brake wire (in red jacket). This has two wires
inside the red jacket, one for 12 volt power on one for the brake feed.
We used the black wire for battery feed, both to the rear of the truck,
and to power the controller under the dash. The other wire (in this
case) is is white, we used that for the brake wire. Wire comes from
rear of truck, the black wire is cut and connected to the circuit
breaker, then passes through the fire wall.
Circuit breaker is mounted to fender.
Used a standard 1/4" spade and slipped it onto on of the un-used fuse
spots in the fuse block - the red jacketed wire: black is 12 volt
supply, the white is being used for the brake wire. So, the wire comes
from the brake controller under the dash, over to the relay on the
fender. The wire wire (brake ) is ran directly down to the rear of the
truck, while the black wire is connected to the 12 volts supply, and is
connected to both the cotroller and the plug on back.
