Yes, that connector is how the computer electrically controls the lock up of the computer. Technically you can run without it but due to the hydraulics of a 700-R4, when you are in 4th gear the cooler flow is greatly diminished. Also, without the converter locked up in 4th, it will generate more heat due to the mechanical disadvantage of the overdrive ratio. Think about how hard that 10 speed bike was to pedal up grades in high gears. You will eventually overheat the trans and believe me they don't like that. B&M makes a nice adjustable control for this based on vehicle speed. Not as good as a factory computer but plenty adequate. You can also just wire it to a switch to manually engage it but it requires you to remember to throw it when you shift 4th. There are other similar products out there but that is the one I have used with the best result. You can also remove the TCC solenoid, drop a steel 5/16 ball in it and put it back in. This method works with no wires needed. However, this only works if your trans has a TCC shift valve. After 1988,or so, they eliminated it from the valve body. Without the shift valve and a plugged solenoid the results are less than fun to drive!
