You need a Revero CIU and TPI and a gateway to translate the revero specific messages to the 2012 Karma messages (and vice versa).
The first two you have to get from a Karma dealer. The gateway is what we have designed.
The silverbox and TPI are identical physically/electrically to what is in the 2012 cars.
There are minor differences with the wiring (maybe two pins) but it does not require a full re-wire.
The biggest barrier -by far, is getting the CIU and TPI from a dealer.
