Hall Effect Speedometer Sender
If you're installing a New Vintage USA gauge cluster into your 1979-1986 Mustang, you'll need this sending unit. The speedometer in the new cluster is electronic and needs an adapter for your factory cable to work. This Hall Effect speedo sender pulses 16 times per revolution for an accurate reading. You'll simply clip your cable into the sender and then plug the electrical harness into the back of the speedometer for a quick and easy installation!
