What is that little black box in the bottom middle of the first pic? Mine doesn't have it.

Riviera/Aurora Maxi fuse cover.

BTW, I added a boost guage today from my Lebaron. It'* an autometer (30 in Vac up to 30 psi boost). It seems to have had better days, seeing how it doesn't go to 0 when the engine is shut off. Goes to 4 inches vac off, and idle'* at -19 , and full throttle shows 4 psi boost. so doing the math I'm getting -15 in vac at idle, and 8 psi boost (given the guage is accurately off). :?

Bottom middle?

I'm pretty sure all the relays and fuses won't fit into one little box with one little connector...

oops I missread it. I too??????

I suppose the gauge could be taped into the vac tree in the bottom pic right??

Tap the gauge into the vac line (using a Tee fitting) that feeds the FPR. That'* where the MAP sensor is tied in on my 93 SSEi for the gauge, and where I tied it in on my 95.

thanks

I just popped into my Boss'* 95 SC Riviera a few minutes ago for a quick visit with my old supercharger pulley from Greenzilla.

The black box pointed out in an earlier pic in this topic in a Riviera is the Evap purge solonoid. It'* in a different place on the Riv due to underhood space constraints. That box is NOT a MAP sensor. Confirmed that the Riv has none, and has no boost gauge (never had the option).

Just hooked my Autometer up again and it shows -21 inches of vacuum while coasting down the road in gear with the AC off.
With the AC on it reads -19 inches.
Shutting the car off settles the needle at -4 inches.
Full throttle is now giving me 5 lbs boost with the AC off.
Have yet to try watch max boost with the AC on.

Temp was 90*, with around 75% humidity.

I always wondered what that thing was! My new boost gauge comes in the mail soon. I am currious as to what I am running.
