It clearly states that every Ridgeline comes with a trailer hitch and 7 pin connector. It doesn't say anything about the connector being wired and the specs breakdown clearly indicate which models came pre-wired. I think it's great that Honda is providing you with a $200 gift card when they really are not obligated to do anything.
Not quite.
In one place it says that "every Ridgeline features a standard integrated tow hitch with 7-pin connector." (read: Hitch and 7-pin connector nothing about wiring)
In another place it says "Pre-wired for 7-Pin connector (2WD) and "7-Pin connector(AWD). read: 2WD comes pre-wired for a 7-Pin connector.
So,
as written they all come with the hitch and 7 pin connector.
The 2wd also comes pre-wired for said connector.
Searching on the Pilot forums it appears that Honda has been claiming for quite some time that various models are "pre-wired" for towing when all they really mean is that you can buy an additional harness to connect the pre-wiring to the plug (no splicing or additional relays/amps required). Other trim levels (such as the Touring) come "completely wired", not "pre-wired". Look around other forums...apparently the term "pre-wired" is not universal from one manufacturer to the other (Honda, Toyota, GMC and Jeep appear to have different interpretations).
