99 Challenger MPEM rewire

[DocBurns]

Hi all, I have a 1999 Sea Dont Challenger with twin 787. I have the same problem alts have as my starboard side motor have lost spark. No voltage coming out of computer to the coil. I am looking into grafting a 1996 GTX MPEM # 278000423. The reason I chose the 97 MPEM is my understanding is it dose not need a DESS to work. So what I am needing from people smarter than me to understand the proper schematic to both the 97 GTX and the 99 Challenger. I have tried to find a legible schematic for the challenger. Any help/ advice would be greatly appreciated.
