I hope someone in here can give me a lead to have this working. I have mounted a MSD 7530, and now my stock tach won´t function properly. Any hints to what to do? I would like to keep the car stock appearing, so would really like to avoid an aftermarket tach. Thanks.
Check online at msd. they may have a solution for your problem. I know that I attached an autometer tach to an msd box and it worked.
