I have grounding strap hanging loose from the back of the engine block. There is another connected to the firewall and one between the battery and firewall. Anyone with a similar model know what it connects to?

 

There's a few of them, that strap goes from the block to the fire wall. There's one from your battery to the block, and I think one to the starter. Pics would help me, if no one else knows for sure.

 

I have

ground cable from battery to front of block

ground cable from battery to body

ground cable from firewall to passenger side rear of cyl head (also has other cables from harness attached to the block)

ground cables from harness to drivers side rear head and I installed a ground cable from there to the firewall
