Hi Ron, the heat shrink alone is not water tight. Your plan to use the  
fusing tape is the very best way to seal the connectors. The fusing tape of  
coarse needs uv protection and even cheap vinyl tape will work fine for  that.

Thanks  to all that replied, I remember that I never had soldered the 
shield and  thought that was the correct method.

I will also as many have suggested  use some heat shrink for stability as 
well as helping with water  intrusion.  Was planning on #33 or #88 tape 
plus some fusion style  tape to help with the final connections.

Again thanks to everyone for  your comments.
