Connect the black wire extending from the pump to a nearby ground. Either loosen an existing bolt or drill a hole and fasten the wire using one of the ¼” x ¾” self-tapping metal screws provided in the kit.
INSTALLATION OF TAILLIGHT DIVERTERS
Prior to installation, determine which taillight wiring system you have on the towed vehicle: a 3- or 4-wire system. A 3-wire system has combined turn signals and brake lights (red turn signals). A 4-wire system has separate turn signals and brake lights (amber turn signals).
INSTALLATION OF DIVERTERS FOR 3-WIRE SYSTEMS
This system will use 3 of the 4 diverters provided in the kit. The preferred location for the solid-state diverters is as close to the taillight assembly kit as possible.
Access the wires for the taillight assembly (usually through the trunk in a sedan and wagon).
Turn ON the taillights.
Ground the continuity tester to a suitable ground.
Probe each wire to locate a “HOT” wire. Turn OFF and ON the taillight switch to verify the correct wire. Label the wire “TAILLIGHTS”. Turn OFF the taillights.
Turn ON the left turn signal. Probe each wire for a “HOT” wire. Watch for the continuity tester to blink with the turn signal to verify the correct wire. Label the wire “LEFT TURN”. Follow the same procedure for the right turn signal, but label the wire “RIGHT TURN”.
Refer to DIAGRAM 3, page 17 for the steps listed below.
Turn ON the taillights. Locate the wire labeled “TAILLIGHTS”. Cut the wire and confirm that the taillights have gone OUT. Turn OFF the taillights.
Strip each wire ¼”. Crimp a ¼” female terminal onto each wire.
