On my distributor I have all 4 of the spark plug wires in. (that's including the one to the ignition coil)

But there's also a set of other wires (2) that come out of the top. What are these wires and where do they go? Ever since i did the head on my 22re I have never found out where these plug into. If you look at that picture above, You can see they plug into a plastic cap. I have that plastic cap - but on the other end of that there's no other wire. So it essentially plugs into nothing.

Are these wires essential?

i can t really see what your talking about. but i have a feeling they go to your coil on the driver side fender-well. if your truck is running still and your happy with it, do what the army says if ain t broke don t fix it.

Ok, I've updated it and highlighted it with a yellow amoeba blob.

My truck is running, but it's sputtering and missing and surging and I'd like everything that's supposed to be hooked up to be hooked up so I can troubleshoot the problem.

That is the coil pick-up wire. It goes to the igniter. Truck won't run at all if it's not connected.

Mine is running and it's not connected to anything. Are you sure? The main wire to the igniter is conencted (the single cable that looks just like a spark plug wire) but these are different wires. These must go somewhere else.

looks like it goes somewhere to me (highlighted in same color you used):

you did a head job, and you can't figure this out

haha, I'm just bust'n yer balls man

yeah it runs over to youre igniter that's mounted right on top of the coil

I bet you have no rev-limiter right now

DupermanDave

This was a picture I found from google images. I thought I put in the original post that it was borrowed from google, but I guess not. I've edited that in now.

So that's for the rev limiter?

abecedarian

It is provides the NE signal to the igniter and ECU. If it's not hooked up the engine shouldn't run since there'd be no signal to the igniter and ECU to determine when to fire the plugs and the ECU could not calculate RPM's, timing advance and when to fire the injectors.
You can see the wire on my 91 here:


It runs from the distributor over to the igniter on top of the coil.

well, amoung other things

just like abe said

come to think of it, it is strange that the engine runs at all

Pistonman

Anyone notice the engine in the first post has an EFI intake on propane?
Not too common.

iamsuperbleeder

I also don't see the fuel rail

how'd he plug up those 4 holes?

already addressed:

Original post edited to add "Image borrowed from Pirate4x4." Below the picture.

So the pic was simply to illustrate the wire in question, not his engine specifically.

Pistonman

I knew that, just stating the fact said engine was on 'pane.
