GM 128K VSS Pulse Generator 3 Wire

128k Pulse generator for vehicle speed sensors. 

LS computers need a 128k pulse reading for the vehicle speed sensor (VSS) in the computer. This will give you the exact pulse reading for LS computers, without needing any additional converter boxes. This pulse generator does not have a pass-through for cable speedometers. This will work for digital speedometers, as well as the Dakota Digital gauge clusters. 

If you have an original style gauge cluster with a cable driven speedometer, like many older vehicles including square body trucks, you will need the SEN-01-4160 pass-through pulse generator as it provides a pass-through cable to thread the factory speedo cable into it, while still providing an electric speed reading. This is often used on older style, non-electronic transmissions, as well as on many older style passenger drop transfer cases with no electric speed sensor.

NOTE: You will also need the SGI-100BT to convert this 8k signal to a 128k signal for the LS computers.
