jeffss396 Posted October 24, 2011 Share Posted October 24, 2011 Almost done converting my 72 from small to big block and need to find out which head the temp sending unit goes in?The car has warning lights and has both underhood wiring harnesses replaced.My second question is,does the blue wire that the wiring diagram shows going to the sensor come as part of the dash wiring harness?The reason I ask this is I cant find it in the engine wiring harness but can see a blue wire that has been cut that is coming out of the middle of the firewall.Which leads me to belive it is part of the dash harness?

BowtieThunder Posted October 24, 2011 Share Posted October 24, 2011 sensor is usually in drivers side head Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted October 24, 2011 Share Posted October 24, 2011 I would ground that blue wire with the key "on" and see if it lights a warning light or blows a fuse but that's me you would have a quick answer Quote Link to comment Share on other sites More sharing options...
iceman Posted October 24, 2011 Share Posted October 24, 2011 I thought that the wire to the temp sender was green. I'm not at the car now (stuck in Taipei and the car is in PA ... 10K miles away give or take) or I would check for you. I don't know if the wire colors were different based on whether the car had the gauge package or lights. Quote Link to comment Share on other sites More sharing options...
