Hi-
I have a 95 6.5 NA. I started having issues with the tranny. It first would not go into overdrive and then quit shifting and is stuck in 1st. I got the main connector off of the transmission and connected a voltmeter to see if I get power when the key is on and engine is off. I got 0 volts. I checked all fuses and they were good. I then removed the dog house to access the wires and what I saw is a mess of wires. See images below. I then connected one lead to pin E on the tranny connector and then guessed which pin in the harness it would be by the doghouse. Does anyone know what pin from the computer supplies power to the tranny? Does anyone have a wiring diagram? Any help would be appreciated. Are the mess of wires standard? Can anyone identify some of the items in the photos?

Thank you.

does anyone have any clue what this is and why its connected to the TCM?
So I changed the fluid and filter in the transmission and still nothing. I jumped pin 5 and 6 to see what codes I get via light signal and I got nothing. When I drive, the RPM's get high and then the transmission shifts for a moment and then downshifts. It will do this and make it to third a few times and then finally quit and just hang out in first. Any suggestions?
