Hey All,
I acquired an old school HKS 60mm boost gauge from my brothers supra, however i can't seem to get it to work the needle stays in one spot. I was told it was working prior to the removal. I couldn't find any manuals online for it as it's so old so i was hoping some of you guys would be able to help me out.

Sending Units wire colors are:
Green
Yellow
Blue

I'm not sure in which order the sending unit wires are supposed to go from left to right. I'm not even sure if they are hooked up correctly in this picture as any combination I've done results in the same thing.

Gauge wire colors are:
Orange = +B
Black = Ground
Yellow = Illumination
Red = Ignition

What is +B? I'm guessing Battery? Where would be a good spot to connect this?

I have the Ignition, Illumination, and Ground all connected.

Thank you for your patience and help.
