Thread: sensor help, going vvl

encountered a couple of sensors that i have no idea where they go, please help if you can and if not thanx anyways,

car is a 91 ser, had the egr deleted so i know that will be one of them, just dont know which

first one is by the iac/aac plugs



second is by the injector clips there are two sensors




last one was plugged into vaccum near the throttle body on my highport, what do i do with them



thank you very much for the help, just needa get these quirks figured out and dist then dropping it in

First pic looks like the knock sensor plug, check on the block underneath the intake plenum. The second pic shows the bottom plug that goes to your EGR solenoid pictured in the bottom photo. The top plug in the second photo is unused, at least on the 91 B13s I've seen. Not sure what plug you have connected to the EGR solenoid in the bottom photo but the plug in the second photo circled at the bottom is supposed to be connected to it. If you have a chance grab or download a B13 FSM to help you with vacuum & wiring issues. BTW if your state doesn't require emissions testing you can delete all EGR related components for the 2nd & last photos and delete the solenoid entirely while plugging the vacuum lines. Just a thought.

i have the knock sensor plugged already, and the egr was already deleted when i got my car when it had a highport,

so first pic idk
second pic is egr stuff
third pic plug vaccum?

tia

Its hard for me to tell cause all I have is my phone but I believe there's 2 or 3 plugs that will have no home..one is the egr another is for that air recirc thing that's on the bottom of high port manifolds an the other if there is one I can't think of off the top of my head..

The first one is the knock sensor plug. Are you sure you don't have a different plug on there? Maybe you switched the oil pressure switch somehow?

Second pic, you don't need either plugs.

Third, you can just cap it off.

both knock sensor and oil pressure were labeled and i put those in the right place

what do you mean by cap it off?

i think the first plug is for sensor/valve that sits under the manifold for the DE motors. I never used it when I swap in my VE motor.

Ahh yes that connects to the IACV valve that is attached underneath the intake manifold for the DE. Yep you can delete that one, don't need it on a VE. As said before pic 2 neither are used & pic 3 plug 'em.

so all sensors pictured go unplugged when going from highport to vvl, thanks guys

how do i cap the last plug or do i just unplug the sensor?

if it runs fine just cut em' off
