Towing Capabilities

If you mean brake controller that is certainly feasible. When we ordered our PW Excel in 07 we asked for a trailer hitch so that we could attach our bike rack. To our surprise it was delivered with the trailer hitch, but also electrical connections and a Hayes Brake Controller (Syncronizer P/N 81725) installed under the steering column. It is meant to manually control electric brakes on a trailer if so equipped. We never used it since we never towed, just used the bike rack.
Hope this helps.
