MSD box and Tach
Having issues with the original tachs in my 87 SR1. From what I read and a few phone calls. The original tachs can be used with msd box and coil. I tested the grey wire from the msd box and it reading the proper voltage. I have good ground and power... I have 4 VDO factory tachs... two claimed to be good take offs... any insight would be great . Thanks

Comfermed need adapters
