The wires for the oil and trans temp were routed through the firewall using a factory wire path. The wires to power the gauges were soldered to the factory wires in the ashtray area and heat shrinked to prevent any future problems with chintzy clip on style connectors. The final step in the process was routing the oil temperature sender wire from the firewall to the temperature sender. We had half of the work done already with our transmission temperature gauge install. In the passenger footwell, past the blower motors for the climate control, there’s a sealed firewall pass through we utilized that exits out at the battery location in the engine compartment. From there the transmission temp wire splits off on its own path towards the back side of the engine compartment and the oil temp wire continues towards the front of the car where the oil cooler is located. Both sets of wires were wrapped in wire-loom and routed mimicking other factory wiring routes and secured with zip ties.
