Anyone have pinout for an 85 TA dash and an 86 TA dash?
I want to convert my car to the electric speedo and newer style guages but have no idea where to start. I know that there are difference in the dash wiring and I am looking for the pinouts so I can figure out which ones need to be swapped when I do this.

I have the pinouts for an 86, and can get and post them up tomorrow. After much-needed sleep.

Here we go; I even dug out an old harness to get the color codes for the wiring. I also added this info to the tech article on my website http://www.hioutput.com/tech/circuits/86pinouts.html
