Black connector CIS where does it go???
 

I am putting the CIS back on (motor out) and to my disbelife i can not find where the last connector goes. BTW I have the green one on the throttle and the blue on the cold start.

Found it! Now if I only knew what the alum thing on right side of the motor with the big hoses going to it where the mistery connector goes was called.

Auxiliary air regulator or AAR?

Make sure you have those black plugs on in the correct locations, there are three that look exactly the same, except one of them is specifically for the frequencely valve. The other two have constant hots for the WUR and AAR. If you plug the wrong one into the frequencey valve it will melt and may cause fire.

Thanks for the tip, fortunately I only disconected the three to remove the CIS and then the wiring harness.
