Reply to "'74 Temperature Guage Problems"

The in-line resistor was 10-ohm and was usually near the front of the engine, taped into the wiring loom. These gauges tend to be inaccurate in the extreme, due to an Italian gauge & a stock US sender for Mustangs. The sending unit was originally in the side of the swirl water tank (smaller tank), but this is a very bad place for detecting water temps. Far better is the stock Ford location for the 351-C, in the front of the block, horizontally positioned. THe sender can be swapped with the pipe plug in the block and the stock wiring is long enough to reach either location. By running both seats all the way fwd, removing the 2 shoulder harness bolts & a few sheet metal screws at the floor, the rear upholstered panel casn be removed. Underneath is a steel panel; remove it and the entire front of the engine (belts etc) is at your fingertips.
