Everyone,
I read a lot of threads on where to connect a electronic gauge that has two wires for 12v. One for constant 12v and the other 12v wire is for ignition switch.

Here is my issue. I read that some people use the ashtray light source and the stereo loom for the 12v ignition wire.
Problem: I have four gauges to install. If I install more than one gauge from the 12v ignition wire, would I draw too much current and blow the fuse?

Second: Can I install all four 12v constant wires to one source on fuse panel?

 

I used the fuse panel and ashtray light for 4 gauges in my previous setup and it worked fine.

 

Are you using the ashtray light for the dimmable wire from gauge. I don't have a dimm wire....I would think too much current will overload the circuit....But I might be wrong.

 

I had Autometer gauge so they were the wire to the bulb.

 

All 4 should have no problem getting switched 12 volts from the fuse box on the driver's side. The gauges should draw very little amperage. You could easily run power from the battery to a relay and have the 12 v switched trigger the relay if your worried.
