Just about to hook up my AutoMeter electronic gauges and was wondering if you could power them in series (as in power through +ive in gauge1 then hook guage2 +ve to gauge1 -ive)?
Just thought this would neaten and simplify the wiring instead of running a power to each separetly.
Run a power wire to each one, if you want to neaten it, at all, run a power and earth wire to one gauge and bridge the positive and negative to the second gauge.
