If you have any problems like you discribed after riding in the rain - grab hair dryer as soon as possible, disconnect data connectors immediately and give them blow of warm air directed inside untill they are warm, repeat it , keep them warm so the water would evaporate fast. DO NOT overheat.
Problem is only front data connector. To solve the problem with front data connector you need to shrink 3/4 inch tubing even 1-2 inch long over incoming comm wire and part of connector. Water enters along comm wire into connector,you want to seal entry of this comm wire into connector with heatshrink tubing.
Rear connectors data and power are not problem, for sure Delphi connector would never leak and rear data connector is placed horizontal so no problem.
Untill you heat shrink tubing over data comm wire entry into front comm connector, always disconnect front comm connector after riding in raain and blow it, do not wait for problem. If you wait water sitting there will oxidize pins with green oxidation and you are in trouble.
