Hi, we just received a new car with a Legend bar. We would like to program the bar so the alley/takedown lights flash in Mode 3, and then disengage when the car is in park. The red white wire is the flasher wire we can hook to the SS2000 Mode 3..is it possible to even do this?


Thanks

Easiest way, IMO to do this now is to use a relay to interrupt the circuit that signals the Legend to flash TD/AL (BLK/RED...or maybe RED/BLK, can't remember). To wire this in, you will have to control the relay with the park signal circuit from the vehicle. Sometimes this is ground, sometimes its positive, sometimes it is polarity changing. You will need to know which and how to safely interface with it. Basically, the park signal from the car will control the relay switch by either powering or grounding it. You would the wire the relay as follows...


85 - park kill signal


86 - opposite potential of above


30 - power input from lighting mode 3 output


87a - TD/AL flash wire from Legend Serial Interface cable


87 - No connection


You can also use a Fed Sig/Unitrol UPKM module, which really is a relay set-up as well.
