Default Wiring harness connector question

I'm trying to figure out what a plug goes to and what plugs I'm missing on my '01 harness. Firs there is a 3 pin connector at the back of the engine that comes out of the little bundle that the map sensor connector comes out of...what does that go to? Next there is a group of wires wrapped in silver heat shielding (that runs down the back of the strut tower on the 4th gens) that all the connectors have been cut off of. I think that the right bank o2 plug goes there and the crank sensor goes there...any ideas?

Okay, I figured out what the lone connector was...evidently I forgot to plug in the cam sensor (stupid me).

All I need to know now are the color wires that go to the crank sensor and bank 2 upstream o2 sensor.

Actually if someone can tell me what all the wires in the crank sensor/o2 sensor bundle go to, that would be great.

It depends on what year harness you are using. Look in the FAQ in the sticky section for conversions and hybrids and there will be a link to PCM pinouts which will have the wire colors. Good luck.

Awesome, that is exactly what I needed to hear! Thank you! Now that just leaves 3 maybe 5 wires coming out of that bundle that are unaccounted for. I may post what the colors are tomorrow...I know one of them is a thicker gauge purple wire.

The large gauge purple wire will be your starter trigger wire. Route it down to the starter and connect it to the only small terminal down there.
