sNs,
You could install a wired brake monitor, either from the TOAD's brake lights or powered from the BB. The wireless connection plugs provide a +12VDC and a ground through the BB for the wireless transmitter to operate. My wireless was less than adequately reliable, probably due the distance and/or the shielding of the MH. Probably cost me $10 for the wire and LED and a couple of hours to install. I've got a set of wireless tranmitter and receiver that is just gathering dust. Haven't used them in 37500 miles. Been satisfied with my dash light. JM2¢...
