At the dist there should be one to power the dist. & one for tach signal. Unplug one & see if car starts or if tach still works. Can't really remember for sure as its been a while lol.
My 1972 tach wire is brown and it has a inline fuse from the factory. Your tach wire will be connected to the negative side of your terminal witch is labeled "tach".
