First of all, I am sending a thank you out to William AKA: olsonreels for providing the doner resistor pigtails, and to jay@EZimmoblock.com and other Rennlist members who lent insight into how to proceed with this little DIY.

Success! I just replaced and relocated the resistors.
Here is a draft as to how I did it and what supplies I used.
Hope some find this useful:

Some good data to collect while you’re running your thermal test would be the voltages at 4 point referenced to ground/chassis: the two connector terminal voltages and the two resistor terminal voltages. This would allow analysis of power dissipated in each of the cable runs and the resistors.
youll need to get an accurate measurement so make sure the meter probes make good contact and wait for a stable reading down to mV if possible. 0.01V at least.

SO now that I installed the resistors we have been having cooler weather so I probably won't see hear the results of my install, HRUMPH!
