Well, from what i remember because its been a while since i looked at it, they start by saying to convert such and such to such and such do this and that, then to convert it back it contradicted itself.

Theres a thread i was posting on i will find it out and it will explain it, it was quite a few months ago. I've looked at an OFAB loom i have and compared it and its very easy to change any wiring to anything.
