Step 7: Connecting the BROWN wire 

 

Follow the wire that connects the C terminal on the run 
capacitor to the contactor. Disconnect the compressor 

“R” terminal wire located on the same side of the 

contactor. This wire is often a heavy gauge wire 
connected to the screw part of the contactor. It may 
also be on a quick connect as shown in figure 5.  

 

 

Connect the disconnected wire to the BROWN wire 
from EasyStart. Connect only these two wires together 
and not to anything else.  

 

 

 

 

 

Step 8: Connecting the WHITE wire 

Connect the EasyStart WHITE wire to the contactor where the wire was removed from in the last step. 
This is typically under the screw terminal on the contactor.  

Note:

 Compressors with an RLA over 18 amps should not use the spade connection like shown 

in figure 5 but should connect using a ring, fork or direct wire connection under the screw. Be sure to 
match whatever method is used for the original installation.
