Ok putting gauges in a 92 D350,got the pyro,trans and boost. Got the first two fixed up but I do not know where to hook the boost gauge up to pull the info for it. I'm pretty sure it would have to be in a vacnum line but just need some help,where to stick the T at. Thanks

 

there's a plug behind the bracket that hold the throttle cables...unscrew it and put a hose barb in it...

I don't have a real good picture...but here's one that it kinda of shows:

I'm not gonna post it directly, because it's the HUGE version in order to see it better...click on the pic once you've clicked on the link to get the fullsize version...

look for the Engine Oil dipstick...directly below that you can see a brass piece with a hose going off to the right and down...you can even see the teflon tape on the lefthand side...

it's just below the bends in the fuel lines, and comes out with an allen wrench...

you just have to drill a hole in the bracket...

On a '92 you still use the same plug, but there's no pesky brackets in the way.

 

hmmm...so one more advantage for the IC...

Um, er, NOooo...
My picture is better.
