OEM boost gauge - need help!

[mrpham]

Hey guys.

Need some help with the wiring for the stock Nissan OEM boost gauge and boost sensor. I've tried going through the Service Manual but couldn't find anything, I think it might be the ADM manual.

But below are photos I took, not sure which wires go from the sensor to the gauge and power, etc...



Thanks!

The service manual on here is for the ADM model.

As for the wiring for the boost gauge, Look here (It was in the useful threads)

I did have a look at that, but it only explains the power loom for the gauge. My car is ADM so it doesn't have those wires.

Need to try figure out what each wire on the gauge is.

This is a guess so don't take my word but if I was fitting this I'd say:

RED = Pos
BLACK = Neg
YELLOW = Ignition On
WHITE = Lights

That's based on my Defi which is same colours except yellow is orange...

Thanks mate!

But now not sure which would be for the boost sensor wires, which there are two.

There are the following wires coming out of the gauge:

1. RED
2. RED
3. BLACK
4. YELLOW
5. WHITE
6. WHITE

The gauge arrived with the BLACK and 1 of the WHITE wires are connected together.

So we can assume the following:

• BLACK & WHITE - ground
• YELLOW - ignition
• RED - dash light (illumination?)
• RED & WHITE - boost sensor
