Smi brake indicator light

Clifftall · 06-05-2010, 02:43 PM

Mine is mounted on the rear view mirror(back) of my toad and I cannot see it in the camera during daylight when I apply mh brakes. I'd like to mount it in the cockpit. Where do I connect this wire? At toad or 7 pin connector?

Thanks Cliff

ps

it's the stay n play duo

I'm not sure exactly what you are asking. I run a SMI Air Force One and I ran a wire from the brake light switch on the toad back to the motor home dash board. On the dash I installed a Radio Shack 12VDC red LED in a 1/4" hole in the dash. From there, the other leg of the LED goes to ground. When I see the red light on, I know the toad brake pedal actually moved, and the toad brakes are being applied.

Thanks John. That's what I want to do. What do you use connect and disconnect that wire from the toad to the mh and what guage wire did you use?

You have a few choices. In my case, I had to use an additional 4 pin plug to run the Air Force One. One of those pins were dedicated to the light, so I was OK. If you are not using any of the pins in the 7 pin connector, you can use them. A choice would be the brake line (5 o'clock in the RV socket) if you're not using it for the SMI, or any other pin you are not using. Backup ( center pin), or even +12V (1 o'clock). You might have to clip some wires if you aren't using that feature for anything, but if the brake pin is open, that line goes all the way to the RV dash.

Because I used an LED on the dash I used a 16ga wire. It was just a handy size I had. LED's don't draw much power so I'd think anything would work.

exactly the same as Pigman....simple and works perfectly...Im thinking of adding a mild audible tone to the light so I dont need to look to verify...something pleasant....any ideas? NOT like a backup alarm

Mine is mounted on the rearview mirror and is a string of blue LEDs. I can see mine in the camera just fine. You could also try tilting your mirror up a little so the LEDs would face your backup camera better. Was gonna move to front but decided not as I can see them ok.
