I recently bought one and installed it myself. I had some trouble getting points F,I,SX getting to stick.I'm also not sure about T1,T2,F1,F2 on the Neo Fix XIV. The led lights up for a few secs and then the unit powers off just like the manual says, but then when I power it back on the led stays on. The manual says that means there is a problem with the bios wires. I have checked and redone some of the wires and still the same resaults. Any help or ideas on what is wrong would be appriciated. Thanks
