This is from another posting. Open the link and look at the picture. This is what I used on my layout. I attached a pair of wires to the fastrack using crimp on connectors. I dropped the wires thru the layout and connected all the wires to a terminal block. One for red and one for black. I cut the wires about 4' long and as needed I lengthened the wires using a butt connector. I added more wire drops to my layout then was really necessary. I ended up using three sets of terminal blocks and connected each block together with a long wire and I then connected the terminal block to the transformer.
I found these at this company. http://www.alliedelec.com/sear...il.aspx?SKU=70078316 I purchased the jumper and can connect on supply line and have 19 lines coming out. The CMB4 Terminal block can be assembled to any length you need. The jumpers are a little tricky to install, but I figured out how to do it quickly. CMB4-10 $6.55 10 slot Jumper $2.29. I bought ten of each.
