Electric Speedometer (NV3500) in non computer truck, Need help

[lts70]

I got all of the parts and pieces from forum members to convert my stock mechanical speedometer gauge to an electric pulse S10 setup so that I will have a working speedo again. Seen in this thread

Only problem is that I failed to realize I needed a computer in between my NV3500 trany and new s10 speedo in order to have the correct pulse communication. I saw a comment in the above thread that mentioned it was still possible see quote and link below.


"If you are carbed, this is what you need to drive an electric speedo. They are easy to find in 92-95 Chevy/GMC full size trucks, its a white box mounted under the ECM. Make sure you take the pigtail as well.

Easy to wire it too. Just de-pin wires you won't be using and braid together the VSS sensor wires to prevent interference. Connect 12V+ switched thru a 2A fuse, ground, and the C15 VSS output to the speedometer input. Calibrate the box using the method above, and done. Way cheaper ($5 if the junkyard even charges you) and guaranteed to work correctly vs the universal Dakota Digital method for $89."
