Re: vacuum to electrical switches on the firewall?
I got the module location from the GM shop manual for 84 model year. I worked for them for 33 years. I do however remember that module did get moved a couple of times. At one point it was mounted out in the engine compartment on the firewall. I never liked this setup. Some worked flawlessly for years (a rarity) and others broke every week. Now GM's electronics are quite good and failures of a particular part is pretty rare. The biggest problem is the VERY small guage wireing and harnace routing, compounded by high underhood heat and limited space. I got out of the business in '99 so it is rare I stick my head under the hood of a late model, but when I do I see they haven't corrected this particular issue. I hated electrical work on any GM truck built after 87, especially the diesels.  Jim

Little stuff left to do is mount winch, wet sand & buff out and build belly pan\running boards. Body work takes lots and LOTS of beer!!!! God, Guts and Guns made America and God, Guts and Guns will preserve it! The worst thing you could do is get into my sights, but that don't matter, you'll never know it, cause you'll never hear the shot Jim or Paladin whichever you choose.
