Thanks, I've got three of the ground wires hooked up for sure, the two on the drivers side of the block and the one that is grounded about half way down the passenger side valve cover to a stud. Where is the fourth one located?
I must have missed it, any help on it's location would be appreciated. Sorry to be so ignorant, this is the first LS motor we have ever done, we've done plenty of the old sbc's, but all this wiring and computers is tough on us old guys.
