Anyone have experience with 4-pin boost gauges

[Kai Hefner]

I'm not having trouble with a DSM today, rather a mk4 diesel golf.

I hooked up a boost gauge that I sourced local. It's called an AutoGauge? Which I just assumed to be an Autometer ripoff. Has a bunch of 4-pin connectors because you can daisy chain other gauges. The bottom 3-wire pin goes to a boost sensor. Can't find any wiring diagrams (found 1 but it's just the hookup spots for wiring the top 4-wire pin into the car). Vacuum line is hooked up to the sensor, sensor is plugged into the gauge, and I wired the 4-pin connector to respectful wires inside of the car. Red for 12V constant, Orange for 12V switch, White for gauge lights, Black for ground. I'm still not getting any function out of the gauge, I'm wondering if anyone has any experience with these guys. Did I mess up a piece of the wiring? Maybe the 4 pin connectors are in the wrong spots? I'm not sure what's happening here. Does not read any vacuum pressure, and when I boost it does not move.

So after looking around I found this.
The wires are:
Black Wire - Earth
Red Wire - permanent +12v DC
Orange - dimmer +12v DC
White - ignition +12v DC

That's how I have it wired. I'm guessing it is not my internal wiring that is the problem.

In your original post you have the orange and white wire switched around.

My mistake, I read it too fast. I'll switch it around but I'm not confident it'll fix my big problem
