after market gauges ?

[blazer2007]

I have a 78 blazer and have installed volt,oil, water and gas gauges which are electric. I have no circuit board on the back ,but was wondering if I can connect the 4 power wires to # 4 on the harness, or is that too much for that . I read that the gauges only take about 3 amps when operating. Just trying to use the harness power instead of running a bunch of wire to the fuse block. It was a gauge panel so I know # 4 is power.

Yes, powering all of those gauges off the #4 terminal ignition feed should work just fine.

The gauges don't draw very much current at all. The 3 amps you read is likely a recommendation for the fuse size. I doubt that all four of your gauges together will draw over an amp.
