LT set me straight on the relay plug. Passenger side footwell, right where I didn't think to look. Plug and relay appear to be the right match.

Ordered up more parts: power steering crank pulley (this engine was in a manual steer truck and never had the option. Strange design, but they would just add-a-pulley onto the front two grooved one), power steering pump bracket (have to use my remote reservoir pump, no big deal, the attached reservoir Montero pump is too deep), and I also spent the extra ten bucks for the two underhood stickers to show the correct engine and the vacuum line layout. All that stuff had to come through Mitsubishi Parts dot com, as Rock didn't have them and I appear to have received the best online prices I saw during a quick search.

The only two things I can't do myself from here on out are to connect the new exhaust to the old system (one or two welds, maybe a short pipe section) and to switch over the a/c lines to the truck compressor after evacuating the R12 and converting it to R-134, hopefully.

The Montero fan shroud IS actually offset a little to the passenger side, which I never noticed before, and appears to be usable in this install, which is good because the engine sits way back from the radiator and the fan will need all the help it can get. Hopefully I don't have to use a fan spacer.

I should be able to test fire this thing as soon as I get the relay!
