Why would you be putting an EG harness on an EF? Do you have a swap?

EDIT: What motor is it and what model / trim level is your car? What Si harness is it? 88-91 or 92-95?

This is the ECT (engine coolant temp) switch, right?
The one that tells the radiator fan to turn on?!?!

on your old engine the coolant fan switch was on the back of the block. on the eg it is on the thermostat housing. you have to extend the wires from the back of the block to the thermostat area.
