I made up a bunch of cables using standard plastic banana plugs on each end to go to the MTH TIU and other devices like the MTH terminal blocks. Also nice to be able to run to a test track.
I would recommend red and black to keep it all straight. I soldered all of mine. Having the quick disconnect makes troubleshooting and testing really easy. They seem to run 50cents to 90c a peice. Monoprice has 5 PAIRS OF High-Quality Gold Plated Speaker Banana Plugs, Open Screw Type, for $6.89 but I have not tried them.
