Older Dolphin Speedometer Setup (8 Dip Switch)

[Curt - TN]

I was so excited that my project truck came with a brand new set of Dolphin gauges until I found out the were 10 or 12 year old new

The speedometer I have has 8 dip switches on the back for calibration and all the instructions I can find have 9 dip switches. I am tied into the VSS wire on the 4L60E trans and as soon as I got 5 MPH the speedo pegs.

Do any of you have set up instructions for the Dolphin speedometer with 8 dip switches?

I called Dolphin and they said they are having a hard time finding documentation on an old one like this. I would replace the speedo but they changed from black needles to red which means I have to swap both gauges and maybe all the sending units.

Thanks,
