problem with a/c compressor swap

[bavareze]

hello,

i purchased the new compressor without previously removing the old one.

allthow the bolts and the mounts for the pressure lines match (almost) there are a few differences with the electrical part and i need help figuring out how to make it work.

- the red plug has only 1 connector on both units and the shape matches
- there is a black wire comming from near the rotor on both units. on the old one, the black wire is attached to the body, while on the new one the wire has been cut and it is loose. shall i attach it to the body as well?
- there is also a white "thing" that is marked with green. what is that? shall i also attach that to the body? it is also loose on the new unit.
- now the tricky part:

OLD PART: the wire comming from the plug together with the wire comming from the white "thing" and the black wire go inside the compressor , and enter the body very close th the rotor.

NEW PART: the wire from the plug enters the body close to the black label, there is another wire comming out from the same place, connected to the white "thing". the only connector that is close to the rotor is the black one that is loose.

what do i need to do to make it work, considering the unit itself is in working condition (as i was waranted)

thanks,
radu

Looks to me as if you have the incorrect pump, Check out the part numbers here:

Not only are the hose connection points incorrect, but the mounting points are way off.......too! That pump has to mate up to the engine block & the pulley has to align with the rest of the pulleys.....

johnny,

actually, the only bad thing about the old unit was the clutch. i will try to swap the clutches instead!
