700r4 lockup wiring

[leftybass209]

Does anyone have any suggestions for what brand and type of lockup wiring to get for my transmission? I know there are lockup kits that rewire the inside of the tranny, and there are those that connect from the outside connector. I know the brands like TCI, Bowtie overdrives, Lokar, and B&M all have different types of wiring to lock up the converter, and when, and how it locks up.

Currently this is the inside of it, and it has a broken wire jacket. I don't know if this is fixable because of the tranny fluid or not. I know that i can solder the wire together if it's broken, for strength, then put some heat shrink tubing over it to protect it. Any help would be appreciated. Thank you!
