Electrical connection (Rectangle Switch Only)
Mount the seat heater switch in a convenient location. Position the
switch so that the marking “HI“ faces to the front of the installation.
Positive power connection:
Connect the positive wire to an ignition power source.
Note: Make absolutely certain that the vehicle electric and power lay
out can support the seat heater power requirements. If
necessary, utilize a relay.
Negative power connection:
Attach the ring connector on the brown wire coming from the seat
heater harness to a suitable ground source on the vehicle.
Affix the seat heater harness with cable ties and assure that all seat
movement is still possible.
Re-install the covers and moldings that were removed during the
harness routing. Assure that all connector and plugs are re-connected.
Check for proper function.

Optional Switch and Harness Instructions
Installation of optional seat heater-switch (round switch)
Select a proper and convenient location for the switch and assure that
the location provides enough space to mount the switch, switch case,
the connectors, relay and connector, attached wire harness and the
fuse. Mark the location for mounting the switch. Drill an approximate
¾” hole for mounting the switch. Assure that the mounting hole is
not too small (side pressure compressing the switch causing potential
malfunctions) nor to large of an opening (improper seating the switch
causing poor or loose fit, etc).

Routing the wire harness
Assure that the location and positioning of the wire harness for the
seat heater does not interfere with seat motions. Any chafing,
rubbing, stretching and/or any stress on the harness may result in
damage to the seat heater as well as partial or total failure of seat
motion. Use cable ties to attach the wire harness. Follow the
harness installation as follows:
With the switch mounted into position, connect the 3 pin connector
from the switch to the harness side 3 pin connector. Assure that the
harness is long enough to make unrestricted contact with the
connector and the switch.
Route the wire harness with the two white prong connectors under
the carpet to reach the individual seat. Allow for as much wire length
as possible to assure unrestricted seat movement.
Run the wire harness with the red and black ground wires to the
nearest ignition source.
