Howdy,

I have the older style non GPS speedometer and it doesn't seem to be getting pulses from the sending unit. Since I installed this quite some time ago my memory is fuzzy. Does the Ron Francis harness plug directly into the sending unit? The instructions show a pigtail connector so now I'm second guessing myself. The Ron Francis connector seems to plug in but the locking features don't engage. Transmission is the tko-600.

All the other connections seem good. Ran the calibration routine twice still nothing...
