The electronic speedo will have a matching sending unit that attaches to the transmission where the speedo cable was attached.
This sending unit develops electrical pulses as the output gear from the transmission rotates. The speedo reads these pulses. The VDO speedo, for example, can be calibrated while you drive through a measured mile. vicrod |

So should this piece that hooks to the tranny come with the speedometer when ordered and is speciffic to only that brand of spedometer? Thanks Ken N.

Thanks to new GPS technology, you don't have to hook a Speedometer to anything! mompanies like Classic Instruments and Speed Hut now offer a GPS Speedometer, and the hook-up is easy-better yet, it's accurate-

Dakota Digital VHX for my 67, came with all the sending units and wiring for all the gauges and the pulse generator for the tranny. The pulse gen works by sending, in my case, 16K electrical pulses for one mile. If you have larger/smaller tires or hi/low gear ratio you can calibrate the speedo thru a series of menus.... if that doesn't work it will self learn by using a measured mile. Super easy plug and play, it is not the LED number type gauge, it's the needle sweep type with digital guts.

I my example, the VDO speedo has a matching sender..
Also it must be ordered to fit the transmission on which it will be used. vicrod |

The VDO speedo CAN be a PITA to set, but luckily there are two methods. The first is to drive a set distance then punch the button. The second is to use the pulses per mile and the only way mine would set - which I did via a separate GPS. There is one caution with the VDO gauge - don't try to rush the calibration - it needs to store whatever you input in its tiny 'brain' and it can take more then a couple of seconds.
VDO and AutoMeter are the only two that I've been able to find that make a 3-1/8" as well as a 3-3/8 speedo and matching tach As far as the sending unit, there are several manufacturers that make a Hall effect sender which is what you need. You do need one that will bolt to the side of your transmission, whatever it is plus use the original Ford tranny driven gear. Here is a good site with a bunch of FAQ's that will help - it was down earlier today though, but is a source. Dave W |

I have a Cyberdyne in my pickup. It didn't come with the sender, but I had a newer transmission with a magnetic pickup on the tail shaft. The cyberdyne unit will use almost any brand pickup on either the rear end, drive shaft or transmission. Calibration was easy using a measured mile, and can be adjusted for tire or gear changes. Good thing was I could get it in a 2 1/16" and hide it out of the way. Been using it for about 5 years with no problems. I fab'd the instrument panel with a large tach in the middle and the other gauges around it. Summit carries a large selection of digital speedos.
