I have a 900 unit, Bratton's part #18730.
The second to last page of the document posted by NKaminar says:
"Hook the battery back up and you'll have flashing turn signals,--with the cowl lights on or off." The info sheets that Bratton's shows online doesn't say COWL, just "...with the lights on or off."
The cowl lights on my car only operate as turn signals. Is there a way to keep the parking light function and turn signal as well?
