This should work, if not we'll try something else.  |
Thanks again Kris,
A nor cal saac member offered to sell me his tach adaptor, but he also mentioned that wiring his tach to the coil made his tach work, so I was hoping that piggy backing the green wire to the coil (negative lead / black msd wire I think you said) should also do the trick. Am I correct? I would be very happy if I were. Then I can get back to replumbing the fuel system. I still think I am gonna run both - 6 lines from the fuel cell through a fuel block to the fuel pumps in the trunk and then just run a -8 line up to the engine compartment with a regulator and fuel filter that I already have up there. Let me know what you think on any of this.
