Ignition problem

[Mountain Main]

I received a Ford Racing distibutor and rotor for a efi 5.0. It works great. I think some body gave me the wrong distributor before.

I cleared the codes in the car and took it for a spin. The check engine light came on so I pulled KOEO code I received code 63 and code 67.

(63) TP circuit below minimum voltage.

(67) Clutch switch circuit failure

I believe 67 is a problem because I wasn't able to install a wiring connection correctly. I wasn't able to get to the switch that is on top of the transmission. So a mechanic and I installed a manual switch inside the car. I push the switch up to start the car and push the switch down when I am driving. I believed the switch tells the computer to read load. I think what is happening is when I do a KOEO test the ECM is not able to test the switch because it is not hooked up

But I don't know what is going on with the TP circuit. I tested the TP sensor and we thought is was good. May be their is some kind of problem in the return line.

What do you guys think the car likes to back fire. This code 63 has been a reoccuring code for a while.
