I don't know what the sender is in the t-56 but it does work directly w/ autometer electric speedometers. get a clip in plug that fits the sender on the t-56 (two wires), ground one wire (I don't think it matters which one, otherwise I luckily picked the right one when I wired mine)and send the other wire directly to the sender wire on the gauge. Then all you need to do is calibrate the speedometer to your car. Autometer gives you a small button that hooks to the gauge to do this. You must press this button while starting the car to get into the calibration mode, then when you reach a suitable location, you press the button again and drive exactly one mile. find an uncrowded road w/ mile markers. Once you drive one mile, stop and press the button again. your speedometer should then be as accurate as most new cars, as long as the mile you drove was really a mile. Hope this helps.
