'79 CJ7 Engine electrical questions

Hey guys, I'm fairly new to jeeps and I'm on the tail end of a full body off restoration. I have hit a few problems rewiring the engine electrical. Probably some very stupid questions, but I have a few extra wires left over. First of all, what hooks up to the starter and from where? I am having troubles with the Haynes diagram. Second, I have a fiberglass tub, and the negative battery terminal grounds to the engine block. Do I need to now ground the block to the frame? Any help would be appreciated, I can't for the life of me figure it out. Probably an important note, I have a rebuilt 258.
Thanks

Here's the wiring diagram you need. Save this to a file, and print it up. You can never have too many GOOD grounds. To the block, to the frame, to the grill shell, dash, etc....

This diagram is clearer than the haynes, but still serves to confuse the hell out of me.

Yea these get me every time,the best way is not to look at the whole picture but to pick out the starter find the wires and use a hi-liter pen to trace where they go. computer pictures are a pain to look at but the other thing i do is save these to a flash drive,take it to a print house and have them do a small run of 10 at 24 inches by 48 inches work for good for wiring diagrams of this size.Way back when i used full scale drawing like these to build a complete wiring harness, so the bigger the better and it's easier on the eye's.

That's a good idea. I should go and get a huge copy printed. Thanks for the tips on here

Probably more than just grounding the frame.
Any electrical device mounted on a fiberglass part needs an individual ground. Nicest is to have a single ground point and run all grounds to this point.
