I bought an 89 single cab pickup with a 22RE in it recently. The guy I bought it from had it all raced out and looking like crap and i'm currently trying to get it back to as stock as is possible. While poking around under the hood I noticed two loose connectors and couldnt find where they would go, one is a single pin at the front of the block, the other is a two pin between the block and the intake mani. Any help as to where these are supposed to go would be much appreciated.

 

air conditioning. the 1-prong plug goes to the clutch, the 2-prong one goes to the idle-up valve (looks like you don't have a/c?)

 

No I dont and im assuming Toyota wouldnt just leave these dangling about out of the factory so is it safe to assume the truck had a/c at one time and it was removed?

 

probably removed at one time. here's my engine (100% stock, with a/c) you're missing the things circled in red, which control the idle when the a/c is on

 

I see....well at least my hopes of installing a/c into this thing are going to be easier than I had originally thought since in theory all the wiring should be there I should just need to purchase all the actual components....thank you very much for the information.

 

many times car manufacturers have all the options on a vehicle ready for upgrade..

like AC

these days if you buy a new car and decide not to get the alarm system, they just don't give you the fob.. even though its already installed..

 

See, that's wierd. Mine is missing the VSV for the grey two point plug, but looking at my friend's truck (which does not have A/C) it had that whole idle-up setup connected to his power steer pump. Is it an idle-up for A/C or power steering? As far back as I can remember, mine has just had the square headed plug in the manifold like yours, streetuner. But no vac line diagrams I've ever found explained it.

 

The idle up is for the ac & the power steering if equipped

 

So..if mine looks like streetuner's, and I have power steer but no a/c, ya think it would bugger anything up if I sourced the idle-up junk and installed it? I'm a sucker for everything being set up right.

 

naw, i think you'd be fine. just look through all the service manuals and find out how to hook it up right.
