This too should be so easy...
Factory tach, Summit spark box, HEI ignition, American Autowire harness, contradicting information. Double taps on the pink wire go to fuse box always hot, correct? The second pink wire tap goes to? The grey wire I believe should go to the cap marked tach but Summit's information says connect this to their grey wire from the box...???
So the ground for all this is??? Just want the dang tach to work without burning anything up. All the original wiring for the tach was gone and wiring this for dummies is not bookmarked.
