That looks like the low vacuum switch.
It should light up the brake warning light on the dash if the vacuum pump fails, or there is a big vacuum leak.
The vacuum manifold is usually mounted on the firewall close to the heater box, though it may have been moved for the factory turbo trucks

The little gold box appears to me to be the voltage regulator for the dash guages.
No doubt your DP mod helps, but why not go 3" since its already out?

Speaking of which, Justin. What does a 3" v-band flange and clamp cost? Thinking of re-doing my DP flange... it be leaking. Dunno if the 3/8" warped or if the "gasket" is bad, put pours out of the bottom of it where the WG is.

cus that's about what i see just running empty on small grades.i don't peak 9.5-10ish until im loaded up going up a good hill with some rpms.that or running up a mountain empty,that'll do it too.
so just be careful.that boost gauge changes real quick when you hook up to something or climb a real hill.
set 'er up so you hit 10 lbs easy when empty,then your EGT's can get quickly out of hand when working the truck (if you do) without an intercooler anyway.
