anyone who has put an ammeter in, how did you wire it? i should have got the voltmeter but i'm having trouble figuring out how to wire in the ammeter.
Thanks, -Nick

ALL of the vehicle current must go through the ammeter. Depending on how yours is wired, the ammeter needs to be spliced into the 10ga wire that powers up the whole truck. If you have the pigtail from the pos terminal, take it loose from the junction block. Run it into the cab to the ammeter. Then from the ammeter back to the terminal block. One of the drawbacks to those types of ammeters is routing all of the current that way. You may want to reconsider the volt meter as it just plugs in a switched 12v on the fuse box...

To make it a little simpler, the little junction box right by the battery, run the wire from there, to the Amp guage, then, from the other teminal of that guage, run it to where ever that wire goes.
I will second the statement of ditching the amp guage and getting a volt guage.
