'86 K10 wiring help needed

[Blake_H]

So I'm trying to figure out the reason the 86 K10 sbc 350 auto wont start. On Sunday my dad and I narrowed down to short in the harness going to the starter. It is/was routed between the exhaust manifold and block.

My question is does the harness look right to you guys? It has a wire going from the alternator down to the starter that is to short to go anywhere but between the manifold & block. Any problem with extending that routing it behind the block like my '87 so it wont melt and short out anymore?





Sorry for the really big photos. I'm shocked I got all this done on my phone.
