I have been looking through some of these TMs and they are awesome but I am struggling to find a good list of what is wired to where in this plug. I ran across one post where Guyfang told someone to test from pin.. to gnd and check the reading. I am not looking to solve a particular problem right now but learn how to answer my own questions and troubleshoot. I thought this manual 9-6115-642-24P would be the right one since it breaks everything down so far. Have I just not dug deep enough or am I not looking in the right book yet? Right now I am searching for the 803A but I have one of each 802A,803A and 804A so I will be needing all of them eventually. Thank you for the help.

(You need to look at the TM 9-6115-642-24. Turn to page PDF Page # 107. Start reading there. They are about the same on all models, but LOOK to be sure.) Right now I am searching for the 803A but I have one of each 802A,803A and 804A so I will be needing all of them eventually. Thank you for the help.
