So I wrapped up the wiring in the engine minus the smoke unit(s) everything is working as it should. I set the loco aside and started working on the tender.
I laid out where I thought the best place for the boards would be and drilled and tapped for 4-40 screws to hold the boards in place. I’m using a MTH trim pot in place of the old one and mounted it above the Original Hole. I started wiring up the power leads to the LTC and RS board trimmed and crimped new connectors. I had to rework the IR wires to be smaller and longer due to the size of the connector that is used on the RS board. I had to cut off the original coupler connector and crimped the proper one that is used. I also wired in the trim pot to the RS board.
Since all of the harness’s used on this are made from scratch I had to make another to connect between the LTC and RS board. Crimping the 1.25mm connectors are a pain. I had to redo a couple because they rolled over in the crimps but in he end if not better than factory...which is not saying much.
I added a 0603 Warm White LED to the top of the doghouse and fed the wires down through the original bulb hole. I didn’t take a picture but I painted the wires black.
I used a 3528 Warm White LED for the reverse light. I covered it in heat shrink and used it zip tie around the old mounting bracket to hold it in place. I ran all four wires together into a 4pin connector and connected that to opposing side that connects to both the RS and LTC board.
I’m currently using the old speakers. I plan on installing different speakers for my loco. Probably going to go what Lionels calls “FatBoy Speakers” Which are just large coiled speakers. Hoping these will deliver more base.
