I recently changed the AC system from an R-12 to a R-134 on this vehicle.

What is your question?

I also added a new compressor, the problem is the AC switch is not making contact with the compressor, so when I am putting in the R134 freon I cannot get it to click on the compressor. I wired it directly from batter + to Compressor and the clutch clicked on and the compressor is now working. I bought a new expansion valve and relay switch but cannot see how or where these switches and valves go, can someone please send me a picture of this so I can replace them, or tell me where they are located?
