PTS truck?

Test this wire at BCM for +12V.

Ignition #1 PINK/WHITE (+) (NOT FOR REMOTE START) @ BCM BLACK 48 PIN CONN, PIN 27

Ignition Sense pink/white (+) @ BCM under driver dash, black 48 pin plug (E), pin 27

You should find a trailer tow connector near/taped to the ignition harness. 10 pin grey Yazaki connector...pin 10 should be a Pink/Green wire and test out as ignition.
