    As always Twisted, you make some good points to consider. I will see what other responses I get and see what I can find out on my own about the '81 factory VSS working with the Rostra setup. I've had the instrument cluster out a few times (fitting my own gauges in the place of the dummy lights) and I made sure to leave the VSS alone! Where though, do the wires off it go? It'd be more pertinent to know for sure if it will even work with the Rostra system but, I'm still curious. When I gutted the computer out, I don't remember the VSS wires being part of the main pigtail.

    greencamaro1981,
    Thank you for trying to help me. I really appreciate it and it looks damn simple to do. Only thing I'm wondering is: That looks like its a setup for a car that has an ecm/pcm etc.. My car is an '81 so it USED to have a computer but, I removed it when I installed the old 327 engine. Did you realize that? If you did, tell me more! Sounds really good to just go get some junk yard parts and buy an aftermarket Speed Sensor!:D

    My 68 uses an aftermarket spliced into the speedo cable transducer as the speed sensor. Seems it was 4 or 8 pulses per revolution.
    My 71 uses the original speed sensor for the t56 magnum, I think it was like 25-30ish pulses per revolution.
    I used the same unit for both cars, just set the dip switches as needed.

    I have to give this thread a BUMP.
    I have searched high and low but, I can't find out if the VSS on my '81 will work on the Rostra kit. I even signed up for a tech number (TIN) on their website but, They still haven't emailed me the number and its been an hour or more. So, no help from Rostra.
    I gutted the computer the car came with but, I left the VSS intact. I need to know if it will work on the Rostra kit without the computer and how to wire it up.
    I'd appreciate any help i can get.
    Thanks
