I wanted to know which harness has the plug for the 700r4 on it? I am finally getting back to work on my 87 vert and can't find it is it part of the engine harness or the one with the guages? If it is part of the engine harness (one that goes to the computer) I think that got threw out so how can I do it with that harness gone completely? thnaks in advance for any help.
