Carbon Fiber Seat Heater Installation Instructions

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
