+1 to that.

I would assume the guy on the right is some sort of hood sensor for an aftermarket alarm system?

The green circle if for a clamp to hold one of the pipes that crosses over the firewall.
Yours looks missing.

The red circle is for an AFTERMARKET pressure sensor (gauge?).
It's not stock.
Looks either HKS or Omori...

the green one is deff for when your car had a/c, it was for the a/c piping - i just took mine out of my 88. its only there if your car came with a/c from the factory. my 86 doesnt have that.

Do you think it goes to the A nipple on my PRofec?

Yea, there's only 3 in. Since the last 1 doesn't line up with the hole correctly.

where do those wires coming out of the back of that thing run to? That would be the first thing I would look for. THEN I would find out where that profec line needs to go. Probably to the input on your greddy pressure sensor. Is that a profec B? I've got the same one I think, but mine is not here at the moment so I can't check for ya. Find out where those wires go to though......

Which thing?! Are you talking about the red circled thing? The PRofec is a PRofec A, I'll try and hook it up to the Greddy pressure sensor tomorrow and see what happens.

Well I traced it to another connector and it goes into a hole in the middle of the firewall, didn't have time today to check behind the center console or dash yet.

Yes, it's a Greddy PRofec A. Well, I went to Greddy's website and looked through the installation manual. The hose that is coming from the IM is supposed to be hooked up to that empty nipple(A) on the PRofec control motor. My IM hose ends at the car's pressure sensor. So do I unhook that and plug it up to the PRofec or add another 3-way joint? Did NOT see the thing circled in red as part of the unit.

I also have a boost guage in the car and it's working, however the boost controller has a reading of 0.0.

The previous owner did give me an uninstall Rebic III. Checked the instruction manual and the 2 black boxes are part of the unit. Did NOT see the thing circled in red.
