I'm useing shark gauges and the sending unit came with the set but no instructions, can any body help with just a wiring diagram, I just don't want to blow up when I turn on the key thanks
The gauge has two leads, one goes to 12 V and the other to the lug on the sending unit. The back of the gauge should be marked.
The gauge may even have three leads, + (12v power), S (sender), and a symbol that looks like a uni drill bit (ground)
Ditto grounding the sending unit. I ran a ground wire from the unit to the frame since the tank is held up with straps and rubber padding. Although I couldn't find a factory ground line I figure the additional line wouldn't hurt.
