mine sint the pro either, but the basic setup is the same.

red wire is +12v
there are 2 balc wires, doesnt matter which one is connected to earth
purple is the sender wire
white is illumination

the brown and spare black are for setup.

to do a custom setup, hold the brown and black wires together, turn on power, it will then go into setup mode, wait for the pointer to get to 7/8 and release the wires

turn power off, then back on. set empty point by quickly touching the wires, then the guage will sweep tot he full mark.

fill the tank, or turn the sender upside down if its out the tank, but remember to earth it lol. then quickly touch the wire again. it should now be set and read the correct level.
