Like the title says, I've got two connectors I'm not sure of. The dark grey one, I'm pretty sure is supposed to be homeless - not so sure about the light grey one. It looks like the injector connectors, but is slightly different, and comes off the wiring harness with the #3 and 4 injector connectors.

This is off a 1992 4runner, manual, no AC, if that helps.

 

 

Probably for A/C idle up VSV.
Notice the plate on the valve cover that has the 2 VSV's? There are spots for 2 more VSV's that you don't have. The extra plug would be used if you had a/c.

 

Yeah, I got it running without them, and they're both pretty dusty inside - so I think you're right, and they're not used on this truck.

Thanks for the reply.

 

they dont do anything i had them disconnected on my old truck i think there for smog crap

 

The lighter gray one is probably for the EGR Temperature Sensor. I dont see you having one in the pictures. Or, it might be for the A/C idle up VSV...

Im not sure about the other one. I have never seen it plugged in on any 22res I have worked on

 

The light grey one us for the ac vsv. I don't know what the darker one is for. I always assumed emissions diagnostics but I'm in Va and it's never been hooked up to anything on my truck.
