Richard Oben (me), North Racecars and Russ are old (1998) Friends and we got our switches from the same place. Which was all good until the unfortunate passing of the supplier. For now we at NRC have stopped making the turn signal set up. Russ and NRC use different approaches but the same base switch. For now everyone will have to be patient as Russ is working on a new supplier. Hope this explains some stuff for everyone. As for the coupe we always sent a MKIII - IV version for the new coupe we would have to see one, but I doubt it is different. HTH, Richard.
