there is a ign source labeled on the fuse box, do i just tap into that wire with the 12v switched cable?
also from where do i get the cable that runs to the starter? thanks for any help guys

You would have to test the connector in the fuse box to see if it is hot in both the "Start" & "Run" positions.

I'm not that familiar with the '73 up stuff but if you have an automatic I think the wire to the starter solenoid would come from the "Neutral Safety Switch".
