Swapping a 74 c10 TH350 to a TH400 and need to know where the factory came through the firewall with the kickdown solenoid wire. Ive watched a few vids and see it could be down low directly next to the bulkhead connector or i also see a wire on some models next to the throttle pedal cable. i have found and purchased a used factory harness and the rubber grommet for the firewall exit is good sized like 1'' or 1 1/2''. The harness attaches to the gas pedal switch, grabs power from the fuse box then exits the firewall for the trans solenoid.
