Not an electrical solution but it worked for me…
When I lived in Venezuela, I had two 40s. On one of them I put what was called a vault over there. Think of it as a metal plate (1/4” thick) that sits on the floor of the driver seat with hinges on the firewall side and hole on the opposite side of where the hinges are (next to the seat). The last part of the system was a rod (1” thick) that is bolted to the firewall and has hole drilled perpendicular to the rod just bellow the dash.
When you get out of the truck, you flip the plate up, the rod goes through the hole in the plate and you place a lock through the hole in the rod.
Anybody wanting to steel the truck will have to tow it because all the pedals are behind a 1/4 “ steel plate. Some people even placed a lateral plate just to the right of the gas pedal so you can’t even reach behind the plate with your hands. That way you can safely leave some small stuff there.
The other 40 had a welded tab on the clutch pedal with a hole on it. The hole in this tab coincided with a hole in a steel angle coming out of the firewall. When leaving the truck, you just put a lock there and nobody can drive the truck.
