I have an AB pair of LL-P1K F3's and the 8 pin spots for the decoder connection have no spots for pins 2 and three. How does track power get to the decoder and do I just cut those two pins off the male plug? Another question the PC board shows three places to cut the trace for conversion to DCC.the traces are embedded in the board..can I just drill through them, or how should I cut them? John
It's not meant to plug an NMRA 8 pin plug into, it's meant to solder the wires from the decoder (after cutting the circuit traces makred with the x and 'cut for dcc'.
It's easier to just do what they did in the TCS instructions and remove the silly circuit board totally. There's plenty of room for a T1, you don't need to pay extra for the smaller M2.

CSX, it is the identical engine. I model GN circa '47-'50. Thanks for the info! I now feel confident to proceed. John
I hear you, Randy,perhaps I should have noted that I am going with the Tsunami and sound. I appreciate the clue about soldering pads as that hadn't occurred to me. Thanks, John
Here is how I installed a T1 in a P1K F3A.
I cut the traces by scraping with my track nipper. Just have to make sure you get all the way through the copper at that point. The three extra function wires (rear headlight, F1 and F2) on the harness were twisted together, then wrapped around to get them out of the way, but still available if desired later.
I used a small piece of double-sided tape to hold the decoder in place.
The headlight isn't the brightest, but it works.
