th350 vs th350c

[blackcherry81]

well i finally got around to installing the b&m shift kit in my trans and turns out it wouldnt work because my transmission is a th350c at least thats what ive concluded there is a wire going into the transmission but its cut off about 6 inches outside of the case so the lock up torque converter must not be functional my question is is there a regular th350 that has a wire going into it or does the wire mean i for sure have a 350c and if so how to hookup the lockup again and what exactly does the lockup tq converter do and if it will improve mileage performance anything any info or opinions would help me alot thanks alot new to the site and its helped me a few times
