Yes, I don't read electrical schematics. It's like shorthand to me.
Lmao yeah I will.
The relays are powered from the battery with a 15amp fuse inline. Pretty much making the relays its own power source and always have power.
I have a switch in the cab that triggers the 1 relay. This switch will need to be 12v to trigger the relay. Just a standard switch from the battery would work.
Reverse light at the back of the truck. I used the trailer plug as it was right next to my relays to trigger relay 2.
I am using reverse wire and switch as a signal to operate the relays. This will make sure you don't have any back feed issues if both signal are tripping relays.
Here are the relays I used if you match the number from my picture above at least most relays are numbered the same.
