Throttle body=Q45.. which plug should I use? I think one is for traction control on the Q45?

The one in my hand is the TPS on the SR20det's TB.

Wholie ass-monkey! Nice car agrabau ! !

That plug looks like a alternator or AC plug, the kind that just click into the alternator or ac compressor

[agrabau]

Thanks thesnail. It's not feeling very nice right now. It's worth about zero to me in a not-running condition.

I guess that connector isn't too valuable to me then. I'm still trying to figure out why this POS won't start.

What color are the wires going to that plug?

[agrabau]

Not sure. Darn. The car is at the shop and I just got home. It's the only other plug on the injector branch besides the 4 injectors and the knock sensor.

That plug is for your Idle-Air-Control-valve located under your intake Mani.

Awesome. I guess the Greddy Mani makes away with that feature. This is what happens when you don't own a nissan... you never learn the way things are "supposed" to be.
