Wiring Harnesses - Touchscreen Grills

What's in This Article?

Get to know the various sensors and wiring harnesses that connect to the Timberline and Ironwood Motherboard. Here you will find information on all the different sensors and wiring harnesses inside the new Timberline and Ironwood grills. 

 

What Is a Wiring Harness?

Traeger uses the term, "harness," when referring to a bundle of wires that does not have a part hardwired to it. Each wire leads to a connector that will connect either directly to a part or to another connector.

Smart Combustion Wire Harness

The Smart Combustion Wire Harness connects to the motherboard and then splits three ways. Two of these connect to the lid sensor and the flame sensor. The third split is not connected to anything; it was originally intended to connect to a grease sensor, which was not included in the final design.

Grease Sensor Connection: The grease sensor was located next to the grease & ash keg. You will find that in some grills, the grease sensor portion of the Smart Combustion Harness runs across the bottom of the grill as if it were connected to the grease sensor. The connector is not actually connected to anything. This does not pose a problem. Do not cut this wire.
