OK, now I'm putting the SC engine back in after a rebuild,
getting close to finished, but, have a few 'loose ends', so to speak, like;
where does the sub-harness for the knock sensor and RH O2 sensor
run, to plug in to the main engine harness?

Its a little square gray plug, can't remember, or find, where it runs to;
can't find a pic in either Haynes or Helms manuals,
everything is in there;
i just can't ever find anything when i need it].

Also, I'm having trouble getting the lower IC tube in position to bolt to the LH bracket,
seems to be hung up on power steering hoses or something;
Should these be routed under it, or what?

Thanks in advance, SC Gurus.

If your talking about where the lower tube bolts under the PS pump...don't is my advice. remove the stud and forget about it. I took it loose the first time I removed them and never used it again. as far as the grey plug here is an engine pic see if you see it in there....

yah, i'm kinda thinking the same on the IC tube....

The sensor harness i'm looking at is under the passenger side,
near the starter. But i dont know if it goes forward from there,
along with starter wires, or up the back of the block to the FI harness,
or.... ? Cant find any loose plug anywhere to route it to....:confused:

Goes forward-plug is roughly next to air filter, down on subframe. It's dark here, or else I would take a pic of mine with engine out.

Thanks Nick!, you're right on the money, i found it below the air cleaner "shelf"; covered up by the A/C hanging over it there. :D
