Nissan control box question?

[Gloucesteman]

I have a Nissan 15B2 which I am converting from tiller to remote controls. My research indicates the the correct box is the RC5B. My question; is there a difference between the RC5B and the RC5C and if so what s it? Thanks

Found the answer. Although the two controllers are the same mechanically, the electrical cable is different. The RC5D control box an be substituted but without the remote starting function (shift, throttle & emergency stop only). It is also possible to purchase and install the RC5B cable into The RC5C ($62.00). Thanks anyway.
