The voltage guage simply needs to be wired in parallel to the (a) power source, this can be from the fuse block, or directly to the battery.

If the guage has a back light, then you will need to wire it to a switched 12 VDC source. The other end obviously needs to be connected to a clean paint free and solid chassis ground, using a star washer and dielectric grease compond.

The amperage / current meter must be wired in series to the power source. Correct polarity must be observed if using a pin / sweeping dial guage.

Otherwise, the guage will be permently damaged.

Both of the guage should be fused within 18" of the power source.

Knowledge is power. But only if you apply that knowledge in a positive way, which promotes positive results in others.

This is a TIM amp gauge, is it that simple? Run a wire from battery to gauge, other terminal to where?
