Wiring Diagram for a 1993 38' Thunder?
 

Does anyone have a wiring diagram or can help me with a wiring issue...I am basically redoing the wiring from top to bottom on my boat and the project had to halt about 4 months ago...Im back on it now but there are few of the gauges that I cannot figure out how to wire up...Namely the gas gauges...

do the sending units have their own power and is just the sending wire wired up to the cockpit? I am thinking that the wires that I need I need are the pink and black wires (at least I thought I remembered the pink wire being hooked up to the sending input on the gauge.... I have 3 tanks total but I don't know the location of two of them (one is in the middle under a big access panel)...

Any help or ideas would be greatly appreciated...
