This is a direct replacement board from Lionel. I included some photos but I don't know what you want to see lots of wires in the way

Not to get off the subject of your correct connector locations, but what made you replace the driver board?...ie; what condition are you chasing?.....the Oddesy system can have a couple things go wrong, including a bad DCDR, .......broken magnets, etc.........just trying to help you avoid getting back into the same problem,...usually, when Oddesy fails, we upgrade to ERR cruise M. This give you way better cruise control,......let us know how it goes,...

Lionel 6-28072  changed DCDR board and since 2 wires broke  off, I changed the wires on the 6pin Micro Molex on the DCDR board & 2 pin Micro Molex on the motherboard Loaded code 84 into the radio board. When I ran it on my test track using TMCC it ran 1 revolution around my oval and stopped. I started it up again  and made sure no spikes in amps. Lights bell whistle ,smoke & RS worked. In forward it ran for about 15 seconds  and stopped. Did the same when I tried it in  conventional. When it stops the lights stay and, no sign of a short.  Would you suspect a bad connection The wires from the 6 pin molex from rear rh 2 black are ground  2 red are hot. 1red & 1black go to motherboard. Seens like I'm losing power to the motor Can you suggest where I should be looking

Follow the two wires for the motor all the way back to the driver, looking for pinched/breaks or cold solder joints. What made you change the driver in the first place?...what condition or conditions were you attempting to correct?.....last time I asked, your reply was “ because the motor tested good when disconnected from the engine” in order to help you diagnose the issue, let’s go back to the first problem, what led you to replace the driver,.....we need the clues,...

The original problem Runs slow, stops, no smoke or sound. My lack of knowledge about what each board does made finding the problem more difficult. RoyBoy was good enough to enlighten me on what each one does.. GRJ  said the tender just does sound. All the motive power is in the locomotive. He was good enough to send a attachment photo of DCDS board w/the sizes of the differend  plugs  When tender is separate from locomotive  RS worked fine that left the engine which has 3 boards Motherboard, Radio board and  DCDS Ody. motor driver board & the motor.  One suggestion was to swap out the Radio board code 84. I also checked all wires for continuity. Disconnected the motor from the drive train (it ran fine on var. dc) I did not fine any binding in the drive train. So my conclusion was the DCDS board  I had no way to test the DCDS board, so I choose to replace it. I find the more I handle this locomotive wires break , I don't know if this is from age, weight of the engine, or me. I am in the process of changing  the 6 pin Molex plug & wires on the DCDS board & 2 pin Molex  on the mother board. I did check  the 2 wires from the motor to the DCDS board they look ok.  Thanks for the interest.
