I did my own transfer from the old toad to the new one. Hardest part is picking up the brake light signal from the brake petal switch. There may be a relay up there you need, so be sure to take the old one out (if it was used).
Roadmaster has good technical support, both on the web, where you can print out installation diagrams, and call them if you need.
