Tundra/Sequoia Remote Engine Start - Main Wiring Harness

If you are a dealer outside of the SET region, please contact the SET accessory department at
(888) 851-2722 or email [email protected].

Inspection Procedure
1. Inspect remote engine start accessory connections to vehicle wiring harness. Check the
T-Taps in the passenger side kick panel to ensure they have a good connection.
Reference the appropriate section below for the correct vehicle. Repair any connections
of IMI or IMO circuits suspected of causing loose connection by removing the T-Taps
and soldering the connection.
NOTE: Exercise care when servicing any wires with black t-taps connected to them.
These wires are extremely fragile and may break easily with excessive manipulation.
