I was pretty sure you had to couple them together, and if Barry reads that, may I say I meant no harm nor was I critiquing his book. If it's there I just honestly missed it and didn't want to trust my eyes. For what it's worth, I like Multi-unit over Lash-up. Truthfully I've never heard the origin of the term, and multi-unit consist seems more on par for what is taking place. Lash up sounds like something you do with horses in a stage coach.

I bought the 20 pack you hooked me up with. Now just so I am in the loop as to how to install them, I remove the jumper, that's obvious enough, but I want to make sure I am seeing this correctly. Based on the shape of the "resistors" is that correct, I have to bend the ends to fit the width of the area I am installing them?
