I am installing a mechanical boost gauge and I want to see if anyone has an idea on where to wire and tap in for the boost on a 17 2.7 eco. There are several threads, but I cannot tell if they are 3.5 or 2.7's. I also need a ground and dash light wire positive. I am installing a Auto Meter 880106 Ford Racing Series Mechanical Boost Gauge.

Thanks,

 

bump, anyone have a wiring diagram or idea where to get boost?

 

with a mechanical boost gauge, just find a vacuum line off the intake manifold, tap into it with a tee. as for the ground and dash light, I wouldn't tap into the dimming, just use the add-a-fuse for a constant 12v so it's just lit while the truck is on, no big deal. Ground? Use any frame bolt.
