ignition problems

ok, just so i understand this.... and so there is no confusion here between us, when i turn the key to the run posistion i get 13.6 volts from the battery, with the key turned on i'm getting 12.6 volts at the positive side of the coil, with the key on the on position i'm getting 1.5 volts to the negative side of the coil. If that is too much going to the coil then i will have to order another brand new ecu wire harness connector and tear all of that out and start over, my question is since i have a 4 pin ignition box can i use the two prong resistor starting over? and if so does this make it easier to wire up? i am a complete tard when it comes to wiring.... sorry but im a visual learner touching feeling and watching i'm not the type of person that can read something and then automatically know what to do, specially when it comes to wiring, that might explain why my coil gets pretty warm while running, i'm suprised it starts and runs with the many volts going to the coil and with it being wired wrong..... I could slap the previous owner of this truck he messed so many things up was a complete retard. i have had to correct so many things because of him.
