That does help--thanks. Sorry about the computer crash. Been there....

IIRC, the thermostat housing has 3? different do-dads wired into it. I didn't want to take the wrong one offf (right on the top front of the engine--maybe I'm looking in the wrong place?) I'll look for the oil pressure senor--thx. I have a manual, but it's for every isuzu engine from 1980 to 1994 or something like that, gas engines included, and it's really not all that good. Especially for things like where the sensors are located. I haven't had a lot of time to spend looking for them, just thinking ahead. A lot easier when somebody gets you pointed in the right direction.

Ah, I remembered another question too--On these engines, are the glow plugs relays automatic? That is, will they turn off the juice to the glowplugs once the glow plugs get hot enough? Or do you have to turn the engine over to get them to shut off? I ask just in case I can't find a way right away to hook up the glow plug light indicator on the dash. I don't want to be burning out my glowplugs.

Thanks all!
