part of your problem is, the camaro dose not have a full frame. so you are grounding your starter through the body. the front subframe to the body to the rear subframe.
this could contribuit to your problem. electicity is like water, it flow's the path of least resistance. by grounding the motor to the front subframe and puting the batt in trunk and grounding it to the rear subframe, you are useing the body as the link.
in a DC circit the flow of the electricity is from negative to posative. by makeing a longer path for this flow you creat resistance. with old tired and well used wireing you are asking for all sort's of gremlin's.
now do not think i am nut's! ask a electrical enginer about this. you will find what i am saying is the truth.
the camaro is what is a called a ground based electricl system. not a posative based. that mean's the switch's control the posative part circit the ground is the constant conection in the circit. oh well have fun! most people do not relize the problem's that can be caused by moveing a batt to the trunk. this is realy important in a unibody car like the camaro. on a full frame car it is not as important.
i bet the light circit is giveing you less resistance so the elctricity is trying to all flow through that circit, thus causing it to heat up. with a starter we are talking about alot of amp's! that mean's a big load on a small wire. think about it, the circit ground's at the front of the body and the back. the wire is less resistant than the body to the flow of the electricity, thus it all tri's to go down the wire instead of the body. every weld and joint in the body resist's the flow of the electricity creating resistance.
well i am getting very technical but this is how you have to look at this. if you move the batt back up front i bet the wire will not get hot. or run a very heavy gage wire from the batt's ground to the motor. one that can hadle the hi amp's the starter uses and offer's a path of least resistance for the flow.
