Before beginning the installation, determine if the seat has built in sensors. We recommend using our SH220CFR kit in this 

situation as it can be cut or trimmed to work around the sensors. Removal of the seat might be necessary to see if a different kit 

is required. 

After determining the type of seat, remove it out of the vehicle and place it on a table or workbench for easier access. 

Remove any screws or clips that hold the seat cover on to the seat cushion and frame. 

You will have to cut the existing hog rings that hold the factory cover on to the cushion. 

Make sure you have extra hog rings and hog ring pliers for the re installment of the seat cover. If you do not have the hog rings 

and pliers they can be purchased through Accele. Pt. #C1000HP for pliers, C1000HR for hog rings. 

This kit comes with 2 pads, one for the bottom part of the seat and the other for the back part. Each pad can be installed on 

either the back or bottom. 

Once the hog rings have been removed, position the pad on the seat with the wires coming out of the back of the seat. The pad 

can be cut if it is too long for the seat. 

Cut across the open spots on the pad and make sure you cover the cut edge with electrode tape. Remove the paper cover off of 

the tape on the pad and adhere it to the seat. Repeat steps for the rear part of the seat. Most of the time, hog rings are not 

needed for the rear seats. 

Route the harnesses for the pads under the seat and zip tie to existing harnesses. 

At this point, the seat cover can be re installed to the cushion using the hog rings and pliers for a more secure and tight fit. 

Do not re install the seat into the vehicle. Route your seat heater harness from where the seat would be mounted or from the 

front to the back whichever is more convenient.

Find a spot on a dash knockout or on the center console to mount the control switch. You will have to drill a hole for the switch. 

Check behind the panel to make sure there is no obstruction behind the desired location. 

Wire the seat heaters. Red wire to 12V battery power, Red/White wire to 12v ignition / accessory, Black to chassis ground, 

Yellow/Green to Parking lights (+) and Blue to ground activation from external remote start 

system( aux 1, aux 2, etc.). Use relay to trigger and give proper ground signal. 

You can now re install the seat back in to the vehicle. When positioning the seat, attach the seat heater connectors from the seat 

to the corresponding connectors in the vehicle. 

13. 

Once the seat is installed, turn the vehicle on and check for full functionality of seat heaters. 

14. Finally, make sure all wires are zip tied and routed under / behind panels for a cleaner
