John Spear tells me that I should use the sender that comes with the Gauge Set I choose in order to get the resistance values correct for the gauge. So I think the adapter route in the passenger side head would be the best way to go.
However the 3 wire ECT Sensor would be the easiest way. Does anybody know what the output of the 3 wire sensor is? Perhaps the output is the same for all gauges?
Sorry to bring back an old thread but I just wanted to post that the plug for the TBI throttle position sensor is the same as the three wire coolant sensor. I'm sure the info should be useful to someone sine the connector cost 55.00 from a stealership. If you don't have your old TBI harness around you can order TPS plug from summit, 6 bucks I think.
