HELP IDENTIFYING A PART SUPPLIED WITH NEWLY RELEASED E-8 DIESELS - PHOTOS ATTACHED

For PS-3 Engines.  If you operate without a Rear Coupler installed and use the front coupler you may damage the circuit board.  That jumper replicates the rear coupler which you have to plug into the connector.  The instructions should show you. G

Unless I somehow skipped over it, there aren't any instructions for use/non-use of this part or any warning about rear couplers at all.  No indication of where to plug it in in the event you would run without a coupler. Something  as potentially damaging to the board as you describe should be clearly outlined in any instructions.

Will contact MTH for some clarity on the issue.

Thanks, George.

I can't explain that unless there is a separate note with the removable fixed coupler.  Here is the instructions:

Fail Condition:

When removing the rear coupler to attach the dummy coupler you will lose operational control of the front coupler on the model. There have also been a few reports of damage to the front coupler drive FET on the engine board.

Corrective Action:

After removing the rear electrically operate Proto-Coupler, install a ¼ watt, 4.7k ohm resistor in the two-pin Molex location where the coupler attached. This makes the system believe there is a rear coil coupler and the front coupler will operate normally. Additionally, the resistor is strong enough to handle any inadvertent rear coupler commands sent to it.

Thanks George.

Definitely nothing like that in the manual that I can find.

I'll read the DCC section thoroughly, which I haven't done. Could be there because they sure do spend a lot of ink on DCC operation compared to DCS which is puzzling to me. DCC takes up the bulk of the manual.
