Is the coach side rv plug typically wired the same for a trailer with electric brakes as it would be for a toad with a blue ox system? The reason I ask is because the coach I have was wired incorrectly compared to how a standard 7 way plug is usually wired. I have the wiring now corrected so that it works with a trailer but I want to make sure it will still be correct if I hook it up to a toad in the future.

The toad wiring is a custom install, but usually follows standard trailer wiring. I wired my own and that's what I did. My RV's 7-pole plug had standard trailer wiring already, including the 12V charging pole. I can't say wheteher it was pre-wired to the cockpit for a trailer brake controller since I haven't crossed that bridge yet.

Seitz372 Toad wiring does following standard 7 pin RV plug layout. Most toads only use marker, left turn/brake, right turn/brake and ground. Some use the +12 VDC to keep the battery charged. Trailers with surge brakes will use the backup light to release the brakes and electric brake trailers with use the brake controller pin.

Thanks for the help. I bought the coach used and the PO had a toad. When I installed my brake controller I found the blue brake signal hooked up directly to the brake lights so it snt a full 12v as soon as you touch the brakes. Then the 12v was connected to the center back up light connector and nothing attached to the standard 12v terminal. I am not sure what they had going on but I wanted to make sure that wasn't somehow the standard toad wiring method.

You could be in for a surprise or it could have been an ideosynchrasy. In my case I have a hard ground somewhere in the line between the fuse for the running lights and the connector. I gave up looking and wired the running lights to the 12 V charging line. Whenever I turn on the key I have running lights. Works for me. ;-)
