Im going to fit an Apexi Boost Gauge shortly on my my94.

I have a yellow and black wire on the gauge and just need to know what colour wires to connect to and location etc.

Im going to put the vacuum hose on the third pipe on the left is this ok?

Thanks
Dave

 

As its a mechanical boost gauge, the only electrical requirements would be illumination that goes to the yellow wire, and the black is an earth.
Thats exactly how I would would wire it if I had it. As for location of the wire, you could either splice the illumination in the steerling cowling, or from the cigarette lighter.

Not sure about the boost pipe on your model/year.

Hope that helps.
