It appears this is a 7.5 microfarad (mfd) capacitor like the ones installed on fans. If your fan motor has two brown wires, in addition to the black and white power wire, just fasten the two brown wire to the leads on the capacitor and insulate the connection with electrical tape and mount the capacitor in some dry convenient location inside the controls section of your unit. Be carefull to mount the capacitor in a location where it does not short an electrical connection.
If the capacitor is replacing the low side of a dual capacitor, for example a 35/7.5 capacitor, extend another lead from the common side of the dual capacitor to one side of the 7.5 capacitor and place the one brown lead from the fan motor to the other lead on the capacitor. If trying to replace the lower side, it is better to just replace the dual capacitor.

Hi,
Yes, that can be confusing...hook the tan wire with the white strip onto the same line wire as the one going to the capacitor...usually the L2 wire....so then in reality you have the two tan wires hooked onto the common and the F terminals of the cap...

The tan/white wire can be insulated/capped and not used. Use and ohmmeter to take a resistance reading between the tan/white wire and L1 & L2. There will be no resistance between the tan/white wire and one of the others. This will be the common wire. Connect it to one side of the contactor. Connect the tan wire to the fan terminal on the contactor and the other wire to the common terminal on the capacitor (that is if you have a 3 terminal capacitor, if you have a 2 terminal capacitor connect tan to one side and the other wire to the other). Then connect the other side of the contactor to the common terminal on the capacitor (on a 2 terminal capacitor connect the contactor to the side that doesn't have the tan wire on it).

The 2 brown wires to the cap in first legend is how they are wired electrically,inside that motor the run winding is common to that brown one they cappped off in the 2nd option, but the powers still going to Run.ommon and run get the juice either way, its just another way to do it, but electrically as to sides of power and where they go is no different, just different way to do it.you can run power in on the Run terminal on the run cap, the run winding and run cap and start cap if equipped are Run to Run to Run.So the hot leg for the run winding also goes to run on the caps, run to run to run.,run winding to run cap to run on start cap.
