Step 1: Cut the trace from the antenna plug to Pin 19
Step 2: Place electrical tape
Step 3: Cut and fit the resistor
Step 4: Practice Soldering!
I used a cold heat soldering tool. It actually worked very well which suprised me. I never used it directly on the point of solder but rather used it to heat the resistor wire well away from the point of contact. Cold heat is neat but you need to be careful to not ever burn out your electronics by shorting the two halves of tool's tip through your board. Heating the resistor wire away from the soldering point lessens your risk of this happening.
