Innovate MTX gauge wiring

[ThunderChild]

im installing innovate MTX series gauges (AFR, boost/vac, oil pressure/temp) and am wondering if anyone knows how much voltage the all pull. im not thinking much, but am wondering if i can run them all off a single SPDT relay.

my thought is yes, but would like some feedback from ppl.

They make SPDT relays in various amperage capacities. Some quite huge. I'm sure a sufficiently large relay will work fine for your purposes.

What would be wrong with wiring them up, getting your voltage, and then the resistance at the wire to get your amperage, that way you know what size you would need.

I also don't see a problem with an appropriately rated SPDT switch.

thanks for the replies, i emailed them and a 30a SPDT relay will be sufficient for up to 5 gauges. so thats what i will do, thanks!
