Engine Ground to Frame?

I have a 91 Sierra, 5.7l 350 and noticed that the braided ground wire on the rear passenger side (still attached to frame) isn't attached anywhere on the engine. The ground on the front is attached, but I don't know about this rear wire. Can anyone help?

I have a 90 GMC K1500 with the 5.7. I did not drive it today but will take a look tonight and post where that strap goes. I am pretty sure it goes to the last intake manifold bolt but will check when I get home.

Great! Thanks, 2000CA Yukon!

On my 90 there is one braided wire that goes from the frame to just under the heater core hoses. A second braided wire goes from under the heater core to the rear of the passenger side head.

Take a look behind the head (between head and firewall), you should be able to feel a bolt that holds it to the head.

Thanks!
