Starter harness 61 GMC wire ID

[63chevy4x4]

I have a 61 gmc and I didnt have any underhood harnesses so i pulled from other trucks and put one togeather but I am having problems with my starter ignition power harness. Im wondering about the 5 blade plug on the passengers side, I have a light green, dark green, brown, wire and a largeer (about 10ga) red and purple wire. I have the red wire for powering my ignition and the feed from the starter and the purple to engergize it, obviously i have it scerwd up, i get nothing when i hit the key, any help would be great!
