    Engine electrical ground locations

    I've tried searching around for info on ground locations while I have found some useful info, I can't find any good pictures to ensure I have the right idea. I know the timing cover location for sure but I'm not sure about the head ground locations and any other places I might be missing. I had a "friend" start my swap for me but he didn't follow through on our deal so I got stuck with a lot of missing stuff and not sure where a lot of stuff went before he started taking things apart. Any pics anyone has would be very helpful. Thanks! Btw my car is an 88 thunderbird. While most stuff is the same I also noticed my o2 sensor harness has two separate ground wires for each sensor while a harness I have from a mustang doesn't have these same wires.

    I have my negative battery ground ran to my engine block at the motor mount.
    I then have a chassis ground from each motor mount to the frame.

    I have negative battery grounded to chassis in trunk, timing cover to drivers side frame rail, grounding strap from head to firewall, and I think there was a ground wire from the engine harness that grounds to the firewall as well.
