Back yard shift control

[yamaha1]

I bought a 91 TALON AWD and after two days it went into Limp mode. I work at an auto parts store and have alot of mechanical background.It has a fried TCU!!! So I called my friend at what used to be the Dealership for Eagles. He printed me a electrical schematic for the TCU. I found that the orange wire and the yellow blue wires are to the shift sol.valves, so I went to ADVANCE and got a three position toggle switch,put 12V to the center of it and wa la I've got a manual shifter.My TCU is already shot so what!!! I am ordering another tcu. Anybody got any sugestions as to where,and how much???
