Heater hose routing

I'm putting my 69 Swinger 340 back together, and need some help with a few things. Could some one post a picture of the front of the intake manifold, I need to see the correct routing of the heater hoses and how they are routed around the fuel line.

Also, the small lead off the negative battery cable, how long is it and where does it go. I know the large lead goes to the cylinder head, and my small lead is broken so I am looking for a replacement.

Thank you. This site has always been a great source for information and answers.
