go to design your own cable http://www.powerwerx.com/adapter-cables/design-build-your-own-custom-cable.asp
pick left 50A sb50
pick grey
pick 10g red/black bonded, 10' or so
pick bare ends ($30) and wire the bare end into the charge control batt +/-

I believe your existing wire is 12g and would not crimp well with a SB50 10g barrel.

Thanks. That seems like the best route. Change the whole cable out. It will run me $39.94 with shipping for the 10' cable plus $29.50 for the 4' tray cable = $69.44

This will be a total of 14' now, but seeing that I am using 10 awg and not 12/14 awg I shouldn't lose any current correct? Could I extend it even further if I use 10 gauge and if so how far without losing current?
Plus, if I remove and replace the total length of cable do I need to add a fuse?

thanks
