Ever since I installed my MSD 6A box my tach has been dead and I haven't been able to getting going again. Can I use one of these adapters on a car without TFI? I've got an MSD ditributor also and no control module (except the 6A) but I've cut the tach wire from the old control harness and used to have it wired to the coil, which made the tach work. Will these "white wire trigger" adapters work on my car and, if so, how do I install them?
