89 5.7 tbi grounds

[SouthernRebel85]

Does anyone have or know where all the under hood grounds are located for the 89 5.7? Thanks

There is a ground from the rear of the Passenger side head to the firewall, one on the right front frame rail near the #2 cylinder exhaust, there is one under the "tee" shaped cover on the firewall on the passenger fire wall near the fuel pump relay. There are also grounds on the intake manifold near the #1 cylinder intake port and on the thermostat housing stud. There is also a ground on the radiator support on the driver side and one on the passenger side fender near the battery. Those are the only ones that come to mind with looking under the hood.

Here's another thread referring to grounds in a 1994 model but there's some good info here...
