Jeep Wiring Question

Help! I have become so frustrated because I am one wire away from getting my '91 Jeep Wrangler running again but can not get a clear answer to my question.

Background- A few months back, my PDC (Power Disrtibution Center) suddenly caught fire while I was driving the Jeep. This happened 10 minutes after I had to have the battery jumped off because I suppose I had left my lights on while at work. Cause of fire still unknown. I was able to find and purchase a used, yet in very good condition, PDC and associated wiring harness. It was very easy to replace because everything could be disconnected and reconnected via connectors.

Now that everything has been reconnected, I am missing the one smaller wire that attaches to the starter. I do have the one that runs from the positive side of the battery connected though. I also know which lug the small wire is supposed to originate from on the starter. What I don't know is where it is supposed to connect to from there. I know that it is ultimately supposed to go to the ignition but not electrically inclined to trace that out. So here is my question:

Is anyone familiar enough with the '91 Jeep Wrangler (4cyl,manual 5 sp) to instruct me as to where specifically I need to connect the small wire wich runs from the starter? Ideally the answer would go something like this: "Use a 10 ga wire and connect it to the 'purple wire with a red stripe' coming off the "blank" relay at the PDC." (Or something to that affect.) Can anyone help? BTW, pictures would really help! Not schematics.

Thanks,

D.
