89 xj aw4 trans manual control 

Thats awesome.Rather like a paddle shifter in letting you chose gears.I think you are on the right track.

Anybody knows what does that "Trans Power" button actually do? I bought a 91 XJ a year ago and have been wondering what it does. Been parked for almost a year and now have bought so many parts for it so i feel confortable when going overlanding. Still waiting on other parts before i take the whole engine apart. Already replaced trans flyid, filter, gasket.

Puede ayudarme con las conexiones porfavor

Did you ever figure out the problem?

I think that's a lot of wires LOL
