Hi all,
I am retrofitting a factory rear auxiliary fuel tank and dash gauge to my poor man's model, but I'm a bit lost in terms of wiring to the sender. The factory loom didn't have everything in place to just plug and play, so I'm just wiring it up to work off its own circuit (ignition powered). I'm running a pollack fuel solenoid with its own switch, so i just want the gauge to read from the sender whenever ignition is on.
I've read the workshop manuals, and I think I have deciphered the gauge wiring but I'm not sure how to wire the sender. I'm talking about this type of gauge...
here's the back of the gauge, according to my interpretation of the EWD these are the wire designations, fuel+ being that routed to the solenoid (which I won't be using), but i can't confirm this is correct as i haven't yet got anything to work. BTW... 12v to any of the 3 coloured wires on the gauge (with white wire grounded) allows the light to come on when you press the button.
so my dilemma is how i should be wiring the tank sender to the gauge, the sender just has two wires, a yellow-red and a black-white. I've run these two wires (with 14AWG) up into the cab to the back of the gauge so I can wire it how ever it needs to be.
i guessed that the yellow-red from the sender would go to the yellow-blue you see on my gauge and ground the black-white wire, but it didn't work. I played around a bit but no luck. i can't rule out faulty sender or gauge, nor do i know if there's anything else in the factory loom (like resistors) that I'm forgetting, but any hints on how it should be wired up will be greatly appreciated.
Cheers,

... if the ohms are different I can pick up a new diesel sender from Toyota, but regardless I'll still don't know if I'm wiring it correctly the way I'm doing it.

83330-90K00. if I could certify which model its from I could be sure I was ordering the right sender (i still don't know whether the sender's dodgy or not, or whether it would have the same ohm output, but its old and I will replace with a new one anyway). I have no idea why the part number doesn't register in the system when doing a Parts cross-reference search, it's never happened to me before.
