Trying to find something to tap this yellow wire to. All my alarm stuff is under the seat and the starter satellite relay is in the driver kick panel. What could I tie too under the dash, near the pedals or steering column? Or even near the driver seat?

From manual:
"Yellow (+) Ignition Input: This wire needs to see true ignition. True ignition is a wire
that shows 12V when the key is in the on position, holds it through crank, and maintains 12V
when the key cylinder returns to the on position. Do NOT connect to the yellow ignition
output on a remote start system. That wire does not show 12V during remote start and the
module will not allow for the vehicle to remote start."

Maybe the power to the fuel pump?
