67 twin turbo dart

Found out that a voltage spike must have done it and the thought woke me up the other morning, I wired in my key on power for the old relay setup so that power was sent to the fuse box causing the spike, since that was the only part drawing power must have gone to it. So I'll find that wire and remove it from the fuse box, maybe run that wire to a inline fuse to power the innovation O2 sensors. Versafueler was sent out as well to have checked.
