W-33 Vehicle Cable and Heat Sensor Switch

Routing the W-33 vehicle cable from the truck bed into the engine compartment, connecting to the +28 VDC and -28 VDC bus terminals TB1 and TB2 on the firewall, and cutting into the engine oil pressure and temperature sensor wires. It ends with the heat sensor switch and its ground wire. A note warns that most wires are shielded.
