700R4 electrical

[POWERMAD]

I swapped out a 700R4 for a 350 in an 87 K5.
There was a plug on the left side of the 700.
What does all that go to? Will it effect the engine at all.
I wouldn't think so but ya never know.

It's been awhile since I worked on AT-Electrical.....but I do think that harness was for a few things....1)shift points (one going to the Trans, and one relaying info back to the ECU),and, 2) Converter lock-up signal. Don't quote me on this though, I haven't played with one of these in years......

If if it a little square 4 prong plug, it is the converter lockup signal switch. Basicaly when you step on the brake it tells the TC to unlock so the truck doesn't stall.
