Step 3. Find the motor home taillight tow harness wires at the back of the motorhome
underneath the bumper.
Step 4. Have an assistant turn ON the taillights.
Step 5. Connect the continuity tester to a ground.
Step 6. Probe each wire for a “HOT” wire. Have an assistant turn OFF and ON the taillight
switch to verify the correct wire. Label the wire “TAILLIGHTS”. Turn OFF the
taillights.
Step 7. Have an assistant turn ON the left turn signal.
Step 8. Probe each wire for a “HOT” wire, watch for the tester to blink with turn signal to
verify the correct wire. Label the wire “LEFT TURN”. Follow the same procedure
for right turn signal and label the wire “RIGHT TURN”.
Step 9. If the motor home has separate turn signal and brake lights, have the assistant depress
the brake pedal, probe each of the remaining wires for a “HOT” wire. Label the wire
“BRAKES”.
Step 10. Use a wiretap connector provided in the kit to attach the brown conductor wire onto
the wire labeled “TAILLIGHTS”.
Step 11. Use a wiretap connector to attach the yellow conductor wire onto the wire labeled
“LEFT TURN”.
Step 12. Use a wiretap connector to attach the green conductor to the wire labeled “RIGHT
TURN”.
Step 13. Route the 45-ft. 2-conductor cable (black/red) under the motorhome (preferably
along the driver side frame rail) from the socket to the front of the motorhome.
Follow existing wires or other protected routes. Keep cable clear of parts, which are
moving or become hot. Securely attach the cable under the motor home to prevent
damage from road hazards. The use of wire loom to protect wires is preferred over
exposing wires to elements.
Step 14. Using 2 of the butt connectors (provided) connect the red and black wires of the
monitor to the red and black wires of the 2-conductor cable.
