the great jumper wire mystery

hello all, im seeing if anyone is familiar with this particular “fix” and has seen it before in hopes to maybe unghettofy my car a little more by implementing a proper repair.
My car was driving fine and then i went to start it and nope, didnt want to “ready” it would ignition on but no ready. i would also have the parking light and a message talking about a parking fault. Car would not key off and would not let me go into park. i had to unhook 12v for car to shut off and shut up. i pulled codes and i got

c2300 c2304 c2305 c2306. after a little research it was my suspicion that either something came a little loose or a poor connection somewhere as is appeared that that the shift actuator was not receiving power or proper ground. after some more reading i looked to the fuse box and low and behold i see a jumper wire coming out of one of the relays. i unplugged the relay re seated the jumper wire stuffed in on of the relay pins and have not had issues since. jumper wire goes under the fuse box i cant really see where it goes without taking things apart. i will get pictures and what relay it is when i get home

 

yes, im trying to figure out what though.

 

if no one has heard of this i will undoubtedly figure it out and report back haha. i could have sworn i saw a youtube video about it but it was in chinese or something.
