While tracking some wiring problems on my '86 GL wagon I went crazy and took the dash out to get the whole picture. Found two parts I can't identify.

 

#1. Can anyone tell me what the mystery part is that looks like a voltage regulator that was mounted on the heater-core case behind the glovebox?

 

#2. What are the two relays and the 15amp fuse for on the vacuum canister assembly that was mounted under the hood, passenger side between the firewall and the strut tower?

 

I could email jpgs of these parts if anyone wants to shoot me an address. <td@oregrownmusic.com>

Part #2 sounds like the vacuum switches.

 

Thing under the dash that looks like a VR is a Pulse Amplifier for the A/C

 

Relays and Fuse are for the A/C and the A/C fan relay.

 

the things in the above picture are solenoids from a Feedback carb model......I don't think that you're car has them.
