Where does the wire that plugs into the knock sensor pigtail come from ?
Can't seem to find the wire that plugs into the knock sensor ?


90 4runner 4x4 5 speed 3vze

Seems I'm a plug short.
I have 4 plugs that led to the rear of the motor.

As you can see there are only two plugs(each side) coming out of the harness that runs along the top of the engine.
I've looked around pretty well for another plug in the motor bay.

Unfortunately my dis-assembly pics don't show the knock sensor wire.
These are fresh pics of re-assembly.

We talking about the 3vze?

On my rigs, it comes up through a notch in the intake manifold almost directly under the throttle body.


It's a lot easier to access if you remove the tb.

Ok, I think I routed the pig tail from the sensor the wrong way, I have the pig tail going out from the back of the intake manifold(lower) just above the crossover pipe.
Looks like I need to pull the manifold and re-route that piggy.

hmmmm..... not even sure how you could route it like that? lol Been a while since I've had mine tore apart tho

I took the thing apart in April, that's what happens when it takes too long to get back together, I was looking at them notches when I re-assembled it.

Thanks gents.

Yep, I routed the wire the wrong way.

Pulled the intake manifold off, re-routed the pig tail.

Problem solved.

Tip: take more pix during dis-assembly, better yet film dis-assembly with a Go-Pro.
