3 Wire Temp Sender

[custodian]

I'm doing an LS Swap in the 85 C10 with gauges. How can I wire the 3 wire temp sender from a 97-98 Corvette/Trans Am be used/replace the one wire temp sender and still use the gauge in the 85 C10?

Does the resistance range of the sensor match the gauge? If no your temp readings would always be off.

keep googling. Three wire is what you need. You've got the sender. One wire goes to the PCM/ECM and the other goes to ur gauge. It will work. If it's off, it's probably ur gauge or wiring on the truck.

@Camar068 has it right. The only reason it's three wires is because it takes place of two sensors that were used on the older engines.
