SI alternator to CS144

Hey guys do I need to solder a resistor to install my cs144 on my 90 YJ or can I just order this from NAPA Part Number: ECH EC82 and just plug it straight to the alternator.

If you have a 1990 4.2 then it's a pretty simple hookup. I did not have to do anything other than wire the plug into the harness. As I recall there is some mod you can do with a resistor in order to swap a delcon style alternator into a 1991 or later.
