Hi Espeelark,
There is a few pics there in my first post ... can you see them ?

Anyway here is my second GP-30 - P2k, even easier - no Sound, I used a LM3, a Digitrax 1" - 8 to 9 pin harness, and 2 LED bulbs with built in resistors. No cutting or soldering. Light filing the screw hole nib for old circuit board.

Just wired the LEDs into the P2K 8 pin top part of the plug with the little push on caps. I timed myself on the lights - about 7 minutes, strip wires,
twist, and cap ... they work great.

Ran it with the other unit - consist works great.

Rolling right along - just bought a pair of NOS - P2K GP30's. They were still new in box, never opened.
Of course to be expected on both engines - all 4 wheel gears were cracked. I can change these out in minutes now.
I buy packs of either red or black gears - reuse the old wheels. The Walthers sets are like $7.50/pair ($15/loco).
Just using new gears, can do for about $4/loco.

I pull off the old resistor board, popped in a new set of LEDs with built in resistors, rewired into the 8 pin plug, just a minor file down of the nibs
on the weight where te screws were for the board. LMS-3S set in there nicely along with 9 to 8 harness on one end. (used 1" version).

13mm x 18mm x 3 mm speaker and box from Crude - engineering, fit onto of rear light notch.

No cutting required.

I did run into a short problem. There was a tiny bit of corrosion on top of the 8 pin plug, after several other attemps to fix, finally found it.
scratched it up and cleaned with Isoprop Alcohol ... fixed it. Must have been a reaction from old flux ... good now.

Runs great. Number 2 will get just a LM3 no sound ...

I don't think polarity of the leads matters as long as all of the speakers are oriented the same way so they are in phase together.

If only every model had that much free space to install modules in!

If I recall correctly, DigiTrax harnesses are the crimped wire type. This means instead of cutting / coiling unused wires you can lift the little tab the holds the socket into the JST plug and simply pull the wire and socket out; saving them for reinsertion later if need be...

Just wondering if anybody knows of any new enhancements or new products on the Horizon ?
Just curious - things seem to be quiet on the home front as they say ...

Perhaps smaller modules ? Software updates ? Added sound files ? ........ Anything?

I know some were complaining about the repeaters not being so good on recent threads ...
