4L60 to TH400 Question

Im going to a TH400 and pulled the 4L60 out. I did a search but could not find an answer. Does the 4L60 wiring harness disconnect anywhere? I followed it up and it runs into another harness and wire loom behind the motor. I havent had a chance to look anymore,and my car is not here at home but at a friends house. Just trying to save some time and ask so I know what Im getting into.

As far as I know it is connected into the main harness. Your also going to have to me flashed to a manual car. I am not 100% sure on the harness though.

i would just leave it in case you ever swap back to a electronic trans later down the road (4l80 maybe ? ), thats what i did with mine, just tape the end up and tuck it away.

It's part of the main wiring harness. I would just pull it up top and leave it if I were you. Also you'll have to tune the pcm to forget about the trans.
