He would rather know now because tomorrow he wants to but on the tires and haul the AS outside, to install the AC and fantastic fans this weekend.
The wire size is compatible.
However the brake wires should only be "stranded wire."
That wire can and will move. Solid wire must "NEVER" move or it will break eventually.
Stranded wire is designed to be moved.
Have the husband change the brake wire to 14-2 "stranded."
Also have him tape up the spliced wire connection, very well, so that it cannot corroded, in time.
