Re: Fan relay install question
The 2 wires on the plug are for the voltage sensing wire and dash light. I personally would get a 3-wire internally regulated alternator and use those wires. This will allow your alternator to put out more power when the voltage drops. The head between 1 & 3 is generally where the sender for the temperature gauge goes and don't use Teflon tape on it. You can put the electric fan temperature sensor where the gauge sensor is now.
