Okay wiring Gurus here it is. Just got through doing a tub swap on my 1967. I have a SBC in it. My question is this: I am using a painless wiring harness and everything has gone pretty easy so far but now i have this snag. After searching the forum I have discovered that the guages are 7v. What I want to know is this. Is the voltage stepped down internally in the guage or guages? Or is there another voltage regulator that I am missing? (I am putting this cruiser together out of literally boxes and not a complete vehicle)
If the voltage is stepped down internally can I throw 12v to the common yellow wire on the back of the guage cluster or will I blow the guages? I am also working on the assumption that the wires leading out to the senders work as the ground for each subsystem. Is that in fact correct? Also, as far as the fuel sender goes is it safe to assume that the center post of the sender goes to the ful guage and one of the perimeter bolts can serve as the ground? Thanks in advance
