Re: whats their fuction???
I know the 2nd is the vac. pod for the a/c stuff and I think the first is for the same, it has a one way valve behind it. As for the plugins not sure.

Re: whats their fuction???
The plug ins go to the A/C compressor. I am pretty sure the first part is the vacuum solenoid for the TCC, and the reservoir is for the HVAC.

Re: whats their fuction???
I agree with 1(almost Its for the torque convertor clutch) and 2, but the wiring in the third pic almost looks like one plug goes to the TCC switch in the first pic. also Looks like one of the wires go to ground? doesn't look like any AC clutch plug I have seen, and it looks to be too short.

Re: whats their fuction???
You're right. I ment the TC clutch switch. I was wrong on the #3 too. I just saw dark green wires up on the fire wall in a seperate harness and just assumed it was the AC clutch harness, I stand corrected.
