What converter is this?
Dan, It's called a Cable X. Here is an old email (1999) :
Dear Mike,
Thank you for your interest in the CABLE X. The Cable X is basically
an adapter that enables you to operate your cable driven speedometer
with an electronic transimission. The Cable X is hooked up by three
wires: HOT to the iginiton; GROUND to the battery; and SIGNAL
to your speed sensor off of your transmission. Your dip switches
located inside the Cable X are set following the Abbott Calibration
Table that comes with your Cable X.
You can adjust the Cable X to meet the changes you make in the
rear end gear ratio. The Cable X will pick up its signal from your
speed sensor off of the transmission.
The Cable X is only $293.99. To order give us a call free: 1-800-643-5973.
We accept Visa, MasterCard and American Express.
We look forward to hearing from you.
Sincerely,
John T. Ware, II
