SMI Duo with Wireless Signal
Had SMI Duo installed last month and thus far am very satisfied (Alpine 36 FDDS Diesel Pusher -- Subaru Outback Manual 2011 toad w/Blue Ox towbar, traditional 6-pin hitch electrical connector). However, I'd feel more comfortable with supplementing the supplied SMI braking LED indicator that I currently have to see on the front end of my Subaru via my Alpine rear view camera. In bright sunlight, the LED on the front end of the Subaru is not very visible and it is pretty small being viewed via the rear mounted coach camera. Two question categories:
1) Anyone have any problem with the SMI wireless radio braking signal from the toad? If so, were you / SMI able to resolve it and how?
2) Anyone know where to find a spare wire in the front passenger or driver side of my Alpine (2008 year) that already goes to the Alpine rear hitch electrical connector? If so, perhaps I could use the spare wire for hard-wiring the SMI Duo brake signaling on/off up by the coach driver area which would be much more useful (viewable) to ensure the toad brakes are used properly.
I have a traditional coiled wire, 6-pin hitch connector and I believe the six pin connectors are typically hooked up as follows: 3 pins allowing the basic hookup of the three lighting functions (running, turn, and brake), 1 pin (white wire) for the ground and two extra pins to provide two additional functions, typically for electric brakes (blue wire) and 12 volt "hot" lead (center - red or black wire). Currently the center wire on the coach connector (12 volt hot lead) is not being used at all (my coiled wire connector to the toad doesn't use the center pin on the coach). Also, I don't think the electric brake pin on the coach (blue wire) is being used and it too appears to be active. Either of these unused wires if available near the coach driver's or passenger's dash area could be used for the SMI brake signaling directly viewable by the coach driver.
I've just ordered the SMI wireless radio to try it out but would prefer a hard wire back-up in case anything affects the wireless signaling reliability. Thanks for any input. ray
