I was converting the 9600 over to a 630 platform today and after pulling the wiring thru the right hand cab access panel the engine oil pressure warning light is on.  I found a red wire #120 I believe to be the culprit is loose and near the bottom right hand cable disconnect. Is this the problem and if it is could one of you combine guru's give me the pinout number to fix it.  Will be ordering a tech manual on my next trip to Deere.  Just trying to avoid the 25 mile trip to town to fix this.This machine has been rewired by the previous owners due to rat damage. 

TIA
