I wonder why they don't include both manuals anymore? Use to be this "Installation Manual" and a "Users Guide" (or "Owners Guide"?) as well. Don't know if I've seen them both lately, but I used to have them on my old pre-crash hard drive.
Just yesterday was working on a friend's rig, and decided that the next time I get my hands on a Centech I'm going to pull all that beautiful tape and loom off, and map it out!
So far though, out of six or seven I've done, I've only had one fault. And that was one of the Blue ignition power wires not working properly. Luckily all I had to do was disconnect it and replace it with the White wire that was not being used.
Never had any other issues that kept them from working. Other than wires too long in some areas, and too short in others, and routed through strange convolutions (the neutral safety wire for instance) they've been relatively frustration free.
