Low voltage wiring of outside condenser & condensate pump

by xela56   Last Updated May 15, 2018 19:21 PM

This is my 1st question here, hope someone can help quick since temperatures are rising. This past winter the cage on my furnace was making noise. It was the fan hitting the cage. I took it out and found it was loose and tighten it. To accomplish this I had to unwire those wires that were in the way of taking out the fan/cage. I labeled every wire and the heater worked fine and no more noise. Now, when I want to turn on the a/c, only the fan inside turns on. The condenser outside does not. I assume it's not getting the 24 volts. I traced the wires coming from the condenser outside and this is when I saw a loose wire that apparently I forgot when I took out the fan/cage. The problem is that I do not know where it goes to. Please look at the pictures provided.enter image description here

Aside from the outside condenser, there is also this pump. kinda tight in together.enter image description here

This last picture shows the loose wire. It comes from the pump wiring. See how it ties in with the condenser wiring from outside ( the other brown wire bundle). The question is, where to I tie in the white loose wire coming from the pump?
