Are you wanting to swap in a modern, electronically controlled transmission into your car but worried about using the original speedometer? Dakota Digital's new Electronic Cable Drive will allow you to do just that. The waterproof unit which can be conveniently located, connects to the electronic speedometer output of any modern transmission and drives a quiet, powerful motor within the Cable Drive unit to turn an OE style speedometer cable. The kits come supplied with a 36" speedometer cable and provisions for GM thread-on or clip-on cables - please specify connection type. Detailed installation instruction included.
