If I may jump into this please:
I have similar questions.
I have installed a battery line from a 2001 Chev 23 foot Class C to my 2007 Honda CR-V.
The 10 gauge line from the coach (+) battery terminal, connected via a 20 amp circuit breaker, goes to the CR-V (+) battery terminal. The CR-V battery is also protected by a 20 amp circuit breaker.
I have a removable section at the hitch to join both ends of this (+) wire.
Note: I have installed separate brake/signal bulbs installed in the tail lamp housings on the CR-V that connect via the 6 pin trailer plug.
My questions are:
- do I need to install a (-) 10 gauge wire from the CR-V to the coach? If so, can I just run it from the CR-V (-) battery terminal to a clean connection on the frame at the rear of the coach or do I need to go right to the (-) battery terminal on the coach battery?
- if I disconnect the power wire when the CR-V is parked for the night will all be ok?
I plan on installing the Stay-In-play DUO as the CR-V brake system.
Thank you for any suggestions/help.
