Spreewald DCC conversion query

On the existing board inside this engine, there are 4 pins, labelled in abbreviated German as the same colours for the motor and wheel pickup. These are just in front of the DIP switches. The loco is supposed to be DCC ready and a straight forward DCC plug in. Yeah right, there is nothing straight forward about anything LGB/DCC! A decoder is supposed to simply plug into this engine and every thing works! Yeah right!
So, I might be a bit simple here, I’ve converted Spreewald to DCC by ripping everything out and installing a ‘proper’ decoder and not a LGB dinosaur, the question is, what are these 4 pins for? Can I just plug 4 corresponding wires to a decoder and it all works? Or do I go back to my tried and tested method or ripping it all out and wiring it up myself.

Cheers

Well it would have been nice if you had folded the ribbon cables out of the way, so we could confirm the sockets are there for a decoder..

If they are, the reading of The Friendly Manual, says to open the DIP switches, plug decoder to board, if necessary plug the pickup and motor wires to the four pins.
If you want to do more, you will need the 6-pin interface cable..

Or you can remove the lot, and work it out yourself..

Thanks PhilP,

Here’s one I made earlier…
This is the one from a previous conversion where the innards were ripped out.
The four wire ribbon cable from the motor/pickups originally plugged into the four pins where the letters Li are printed.
The pins I’m referring to are in front of the DIP switches. If I simply attach the four wires from a basic LGB decoder to these pins, and change the DIP switches, does that activate the decoder, and is that it for a conversion?
