Does any Mfg make a wiring harness for a decoder that also includes a dummy plug so the locomotive can be use in either DC or DCC mode?
I know there are dual type decoders but just thinking along this line at this time
Why would you want to?
Remove shell, swap plug for DCC. Remove shell, swap plug for DC. Why? Just get a dual mode decoder and be done with it.
It was my understanding that a locomotive does not perform as well on DC when equipped with a dual mode decoder as it would running strictly DC
They perform fine unless you’re one who runs at max speed. Having a decoder will reduce the maximum speed a bit. Most run much lower so it’s not an issue.
how do they do MUed with conventional DC locos on DC?
The TCS decoders are very good for DC operation. They act like there is no decoder at all.

Now that is one area you might have a problem with as a DCC engine will start moving at a higher DC voltage. But I never had any real good luck MU’ing engines with DC to start with.

If you use decoders that have 9 pin connectors on the decoder, Digitrax sells 9 pin dummy plugs that you can put on in place of the decoder to convert the loco to plain DC. This will work even when the decoder has to be hard wired. FOr locos that already have 8 or 9 pin plugs, they always come with a dummy plug so the loco can run out of the box without a decoder. Just don’t throw them away.
