Pre-Installation Summary – Overview

1. Remove the existing front or rear seat covers. 

2. Take note of whether the covers reattach by way of Velcro or Hog rings. 

3. The Wire Connector with Purple & Black colored wires is seat the connector which will enable the use of both 

High & Low temperature functions. 

4. Place the heating pads on the seat and at the Listing Reattachment Area mark the pad with a pen. You will 

be cutting 2 holes per pad. The holes should be equidistant. 

Example:

 If your listing length for Velcro or hog 

rings is 12’ in length then, make a hole at the 4” & 8” point. (The Seat Heaters may also be trimmed in length) 

5. Now separate the protective adhesive backing at the backside of the heating pads and carefully align your 

pad and holes with the listing area and press the pads against the seat foam to secure the pad in place. 

6.

 Reinstalling the Covers:

Tip:

For Backrest Covers, turn the cover inside-out and roll the cover back down 

the backrest, then reattach the plastic clips. For Seat Bottoms, start by attaching your Velcro or hog ring listings 

and then proceed to work outwards. Don’t work from front to back or from left to right – start from the middle 

then work outwards! 

7.

 Switch Location:

 The diameter of the hole for the switch is 13/16” or 21mm & the most common location for 

the switch is on the plastic trim located at the side of the seat. 

8.

 Power Sources:

 The most common sources are the Accessory Panel, Power Seat, Cigarette 

Lighter/Accessory Outlet, and Steering Column. However, we recommend drawing power via a relayed key-

start trigger sourced directly from the battery. This avoids onboard electronic system interference. 

***Warning:

If you are installing seat heaters into a vehicle which has a 

Passenger Side Occupancy 

Detection System for the Air Bags

, You Must Observe The Following: 

When you remove the seat bottom seat covers, identify whether or not the seat is equipped with topside 

sensors. They are usually visible and resemble flat circular disks which are interconnected or rectangular in 

shape. If you are uncertain, you must contact a service department professional for confirmation. 

Toyota, Kia and Hyundai usually locate the sensors on top of the seat bottom core foam. 

Honda usually locates the sensors on the face of the seat backrest. 

In either case, for that particular seat (usually passenger sides only) use only the 2-temp wire connector with 

one of our seat heater pads. (Disconnect one of the other pads – you will not need it) 

*The dual temperature wire connector is attached to a black and a purple wire. 

This will allow dual temperature function with the use of only a single pad. 

Do as the factory does!!

When you purchase a Toyota Sienna from the factory they only heat the passenger side backrest. The Seat 

Bottom has NO Heat. 

When you purchase a Honda Odyssey from the factory they only heat the passenger seat bottom. The Backrest 

has NO Heat. 

** Reminder - Whenever a cover is removed and reinstalled Please have the Dealership Service 

Department Recalibrate the Seat Sensor to Register “0” –Zero.!!
