My 68 has idiot lights. The temp sender on the car is the nail type for gauges. I bought the plastic adapter and plugged it in. It tends to slightly show lit up on the dash. The car isn't getting hot. I've got an NOS single prong unit coming...I hope it resolves the problem. Anybody had similar sender issues i.e. using the gauge type sender on indiot light dashes?

the senders are different for cars with and without guages,that is the reason jamiel
