Bernardd Posted March 20, 2012 Share Posted March 20, 2012 Gentlemen, I'm trying to use the stock water temp sensor on my 72 but the wiring from the main harness to the sensor is missing. It may be cutoff somewhere in the engine bay and I need to know where the sensor makes it's way into the engine bay or at the very least where the wire runs from the sensor into the main harness. I know some of the v8 swap guys use the factory guages so some of you must have done this. I've installed an L28ET using the 83 harness and have that sensor wire dug out ready to make the connection.

OldAndyAndTheSea Posted March 21, 2012 Share Posted March 21, 2012 I'm pretty sure this wire (I don't remember what color it is, I imagine some sort of yellow/yellow+black signal wire) is part of the harness that comes out of the hole in the drivers side radiator core support.

Miles Posted March 21, 2012 Share Posted March 21, 2012 (edited) It is an 18 ga. yellow and white wire. It is in the harness that runs from the passenger side of the engine comapartment, then crosses in front of the radiator, then to the driver's side fender then to the temp sensor.

Bernardd Posted March 21, 2012 Author Share Posted March 21, 2012 Would it by chance go into the main harness by the alternator/regulator? Quote Link to comment Share on other sites More sharing options...
