Having previously described modifying the plug and wiring for fitting non-Hornby decoders to the Hornby Huntley & Palmers Peckett W4 and Sentinel diesel shunter, I failed to take a photo of the decoder actually in place to show just how easily the TCS M1 fits inside. Being smaller than the Hornby 4-pin decoder, there is room to spare, so I use a small blob of Blu-Tack to stop the decoder moving around.

Having just received a second Peckett, this time the Peckett pale green Dodo, I went through the same process again, only this time it took half the time to do and came out a little neater as well.

The blue, white and yellow wires are neatly bundles out of the way with a spot of heat-shrink tubing. If I ever want to add lighting or other functions, the wires are still available for use.
