ok just looked I got the start of the ground strap daisy chain webs on that stud and a fat ima say 10 ga black wire on a ring terminal that's it don't see this ring terminal shared by two wires what do these wires do where should I look for them?

 

Don't have a diagram to tell me for sure?
Should be in the same general location exiting the drivers compartment/wire loom as the other wire.

 

found it the two wires sharing the ring terminal never got put back on when I put on the new cylinder heads put it back on and went on quite a little adventure truck never even flinched thanks
