    I finished my TR7/lLS1/8.8/Powerglide swap a couple months ago. Its a complete blast to drive however my factory TR7 tach isnt working. I have Megasquirt for engine management and it should work as wired, but I have not double checked the wiring. Is there anyone who knows if you need to add a resistor to get
    it to work?Name:  tr7new.jpg

    So no DIY help, just selling products on this forum?

    Tony,

    This is simply the best solution we have. If we had a DIY we would certainly post it. We have to send out the tachs to be modified by an electrical engineer to work with aftermarket ignition.
