gauge dimming

[hobbzz]

I will be installing three autometer gauges in a couple of days. I will be using the extra wires on the back of the radio for the power, so that the gauges will dim with the dash lights... Will the extra radio wires be able to handle the power required for three gauges? I've only heard of people running one gauge off of that...

I run three guages off that wire with no problems.

Thanks for the info!

The wire behind the radio is the one that dims. For ignition-controlled constant 12v, I tapped in at my fusebox. Check Projectwrx.com to see how Jorge wired his.

Are these mechanical guages if they are they only need a ground and a power for the light source, so if that is the case the wire at the radio is fine. If they are electrical and also need a twelve volt switch source the one at the radio is fine also.

2 mechanical and 1 electrical... Do you guys know of anywhere online that I could order npt fittings to install my boost gauge? No one in town has the right parts...
