Question ? For those with Trans Performance button in TA

Well I need some Help(Again) I have just bought a Stock Trans performance button (the one in the center consoul of a 95 TA) I already added the wires to my computer for the button. But now I need to know where the wires on the button go to. The wire colors on the button are Black/White stripe, Brown, Light Blue, Dark Blue, and gray. Can anyone tell me what wire is what. I know one of them is a ground and one might be parking lights not sure. Thanks for any Help.

This link doesn't look too helpful.

And this link used to have all the info, but its gone now.

Light blue should go to the PCM

Gray should be the power for the light on the switch

Black/white should be the ground, for the light

That leaves brown and dark blue, which I can't find any info on. A guess would be that one of them is a ground for the switch... what the other is for, not sure.

What I'm curious about is how this is going to work on your 97? Got a 94-95 PCM. Or those wires you added do something?

Good luck

I have a OBDI 94-95, in my car. But believe it or not it works on some OBDII cars as well. I put a switch in my friends 96(OBDII) and it works great. The tables are in the OBDII, but sometimes they are have the same values as the normal mode. If you have LT1edit for OBDII you can change the values. Bottom line- Some OBDII cars have the Performance values in them amd some don't. It must depend on when exactly the computer was made. I also posted this same post in the LT1 section and shoebox responded with the wire colors, so if anyone needs the colors and where they go look in the LT1 section. Thanks again for responding!!
