Title: Digital speedometer problem?
Post by: jleews6 on April 04, 2010, 01:07:38 PM
As some may know im putting a complete tbird interior into a mustang and a problem i am facing now is the speedometer. I know that both the buttstuffog and digital speedos ran on a VSS from 85 on but how do they hook up???

Like for the buttstuffog one is there a regular cable that connects to the speedo and then plugs into a sensor mounted on the tranny??? I mostly want to know how the digital ones hook up but I do want to know how the buttstuffog ones are too.

This project is a lot harder than I thought :hick:.

vss is a sensor on the transmission that goes to the tranny and replaces the speedo cable. The speedo on our cars do not have a speedo cable.

Yeah sorry bout that I was reading something about the 83-84s and was confused. I did read about people wanting with 83-84 cars wanting to switch to full digital would have to hook up a voltage regulator for the sensor do you have any idea on how I would do that. I did find a link to COOL CATS for the wires from the cluster so that helps alot :D.

Good luck with that.I really find it amazing when you guys swap these kind of gauages and do this kind of work.I've done a LOT to the Sport,but this stuff is awesome.I want aftermarket gauges.Too bad they'll cost 3 times more than I paid for the Sport.LOL.

The speed sensor operates off the dark green/white striped wire in the cluster wiring harness. This wire is also the one that ties into the Tripminder.

This kind of information is helping me to adapt the 95 Mustang instrument cluster into my car since I am using the Mustang dash. I am getting to know the wiring systems so well that it is scary! But I always had a knack for things electrical! I guess it helps that my father is an electronics technician and one of my grandfathers was an electrical contractor.
