VOES Switch

1986-1991 VOES switch should have a ground wire with a ring terminal that terminates at the top center motor mount bolt to the rear head.
(1986 may have originally grounded to rear of center mount bracket but it's safer to use the bolt thru the head due to paint/rust/poor grounding condition there)
1992-1993 VOES ground ran to a pressed/welded stud to the rear of the center mount bracket (dedicated ground point).
1994-2003 VOES switch has a ground wire in the same connector block as the signal wire and is grounded by the main electrical system grounds.
