Ok, I installed my Trick-L-Start today. I couldn't wire it the same way you did. On your picture, I couldn't read what the lable on the fuse block above the garbage can read, but mine said chassis battery fuse block, so I knew I couldn't hook the yellow wire there. There are two main posts in that compartment that all the positive wires lead from, one for the coach batteries and one for the chassis batteries. So, I hooked the yellow wire to the one marked coach batteries and the blue one to the post marked chassis batteries. The ground wire I put the same place you did. Looks like everything is ok. As soon as I hooked up the ground wire the charging light came on. Thanks again for the idea. Now I don't have to worry about turning that key after sittng camprd for a long time.
