Will S/W gauges work with stock sending units?

Doesn't it depend on the resistance the gauges are designed for and the resistance the sending units produce ? It not universal.
yeah, that's pretty much the game.

i just went thru this whole hoopla with a temp & fuel gauge, thought i'd save a few bux and order up some "universal" units, and after a few rounds of dicking around with crap *** crap quality and rubegoldbergain fittings and tearing my hair out over how much fuel was or wasn't in the tank (and no, pushing the truck isn't an option), then questioning whether or not the temp gauge was accurate i just took the hit and ordered up the SW units.
