Hello everybody, I hope somebody can help me... I have a 72 project car near completion, and the turn signals are from an 74 (donor car), does anyone have the correct color to color wire diagram to attatch the 74 to the 72 wiring?

The '74 has all wiper functions on the steering column, and a left side turn signal; the '72 has only the on-off and wash function on the column; the speed control is on the dash. In addition, the 72's wiper switch is also the turn signal. To do it properly, you'll have to use the 74's left side turn signal lever assy as well as its wiper switch. You'll need the factory wiring diagrams for both the 72 and the 72 to determine wire colors as they're some differences... You'll also need to either re-use the multi-prong plugs from the 74 or put individual terminals on the 72's wiring harness to plug the wires into the switches.

Good luck

Mike

both '72 and '74 cars were wired 2 different ways, so there's a possibility of 4 combinations.

But at least the motors are the same: at 71.5, the complete system changed in function, and crossing THAT line is REALLY ugly... the park circuit logic is completely different!
