Pre-Installation Suggestions
1. Disconnect the negative battery cable and wait
for 3 minutes before beginning installation, to
avoid unintended air bag deployment. Note
and record any anti-theft radio codes prior to
disconnecting. Figure 1
2. If vehicle is in Electronics work area,
proceed to step 1 page 4. If vehicle is in
Leather shop, proceed to next section
“Install Heating Elements”.
Install Heating Elements
1. Remove seats from vehicle per vehicle’s
service manual and place on a clean work
surface.
2. Remove seat covers per vehicle’s service
manual.
3. Caution: The heating elements must be
installed wrinkle-free.
4. Obtain the back heating element. Remove the
protective layer from the element’s double
sided tape and place it onto the seat back foam
roughly centered on the foam from side to side
with the top of the element just below the
transverse listing (tie bar trench). Figure 2
5. Route the element wiring harness down to the
bottom of the seat back, inboard of the hinge
cover and under the seat.
6. Repeat the process above for the seat cushion,
laying the heating element transversely such
that it does not interfere with the horizontal
listings. Figure 3
7. Secure the seat harnesses to the tie down bar
and run down the side listing to the back of
the seat, then down. Re-attach seat covers.
Figures 4-5
8. Replace the driver and passenger seats into the
vehicle. Connect the seat element connectors
to the main harnesses. Secure the harness
with wire ties and allow adequate slack to
prevent damage during seat adjustment.
