Resisters for gauges

Resistors don't work and it doesn't make any difference whether positive or negative.

Oil pressure, temp, and gas gauge are electrical. You need a voltage regulator for your electrical gauges.

Commonly called reducers. They are available in many forms and styles. These are from Speedway.

There are dozens of threads in the past on all the different types and how to wire them. Runtz are the most expensive and you need 3 of them.
