Im adding an ac system to my non ac truck, what wires do I need to add to my harness and where do I them to? 2nd question does it matter what way the pulley goes either counter clockwise or clockwise? 3rd can I use any old condenser or does it have to be specific?4th where would I get hoses to go to all the parts to connect the to each other

Far more information is needed to answer your questions!!
Are you attempting to install an ihc oem integrated hvac system? The integrated systems used a dedicated control head along with some relays and vacuum motors.
What pulley are you asking about? Is this the compressor clutch you are asking about?? What compressor and what mount are you asking about? Where are you going to mount it and how? The compressor/clutch will rotate only one direction, that is determined by crankshaft rotation direction!
All wiring information is contained in the appropriate section of the service manuals for the hvac system.
If this is an "aftermarket"-type add-on, then the wiring is specific to that unit and we have no way of knowing what you have!
The oem condenser can be used with any system, however it's efficiency and design make it not the best choice for using r-134a refrigerant.
Any competent mobile a/c shop can make up appropriate plumbing, the end fittings must be properly crimped...and fittings are selected based upon they type components selected. All mobile hvac hose today is of the "barrier"-type construction and must be used with appropriate fittings designed for barrier hose.

Post all pictures of components to be installed and we will then proceed.
I need to know the brand name if possible for the under-dash evaporator assembly and see a pic of it's control system.
If installing an oem-type compressor mount and york/cci compressor from an sii donor, then you need the crankshaft pulley(s) that went with it along with any "shim"-type spacer that might have been installed on the donor engine.
And you need to plan to replace the receiver/drier with a new component, do not attempt to re-use the one you May have that was with the donor system. A receiver/drier is a maintenance item, just like an oil filter, it's moisture-contaminated at this point and is not usable.
If you are going to charge the system with r-134a, then the replacement receiver/drier needs to contain a dessicant that we refer to as "xh-9". And a high pressure cut-off switch needs to be installed in the high side plumbing for system protection and to meet current federal guidelines for retrofit.
The compressor will either have manual service valves as part of the plumbing system, or if a last gen system it will have schrader-valved 1/4" flare service ports with caps. For use with r-134a, the service ports must be converted to r-134a standards using the appropriate design conversion kit to allow the manifold gauge set hose connections for service.
This type work is not for the un-trained diy'er with no prior knowledge of the mobile hvac system components and service practices!
I'm moving this thread to a more appropriate sub-forum.

That is a typical "universal" york/cci compressor and has no clutch mounted.
The receiver/drier is useless as it's been open to the atmosphere and is contaminated. A used rd is useless for anything except conversation piece. A receiver/drier is a maintenance part that should be changed out on a periodic basis.
One of the shots shows a circuit breaker used for system electrical current feed and protection. I see no other control component nor do I see the evaporator assembly which will include additional electro-mechanical components.
The "clamped" hose fittings tell me this was an system running on r-12 that had either been repaired due to a previous hose /fitting failure or was part of a boneyard parts install.
The compressor mounting bracket appears to be a homebrew/fabricated item that is similar to one of the mounts used by ihc for an oem app on some platforms.
The two manifolds on the compressor are monoblock fittings with 1/4" flare service ports hopefully fitted with schraeder valves, other wise the fittings are useless. Those are also barb fittings that can only be used with non-barrier hose material which cannot be used with r-134a refrigerant. The compressor has been open to the atmosphere and is now internally contaminated and will have internal corrosion and all kinds of trash inside. Ya might use it for an on-board air system if it's not seized now, but I'd never attempt to use that in a refrigeration system...it's only value at this point is as a core for a reman/exchange.
That bottle of r-134a I see in the background is not the right stuff to charge any system with! It has a synthetic oil included that is not correct for that compressor!
Any york/cci compressor should run only an "ester" oil when used with r-134a.
In order to identify "which" system this is, I need to see a clear/focused pic of the front of the evaporator system complete with the control system.

Mm ibought this as a used system. So all that u see is all that I have. As far as the 134a in the background that was for another car. For the compressor does IHOnly have such a part?drier I can get locally same rith compressor, however at 220 bucks for the compressor its kinda spendy. Will the bracket work for a york comprrssor?
