I'm trying to hook up my boost gauge. I've searched and can't find anything. This is the el 1 , doesn't have the meter box or any of that.

Gauge; these are the colors coming off of it.
Yellow
White
Red-power
Black-ground

Then the actual sending unit, has three wires and the vacuum nipple.
Black
Red
White

How do you guys hooks yours up?

 

C'mon there are alot of people who have viewed, someone has either hooked one up or knows. This is the first generation one, Comes with the gauge, the four wires, and then the vacum box with only three wires coming out of it.

 

up

 

Bump for looking. Idk. Ones gonna be a signal wire. Maybe the 4th off the gauge is for another sensor of some sort?

 

Bump for someone who has installed one before.
