if you could pull and take pictures of the wiring and make some type of chart for the forum that would be amazing and really help me and everyone out who wants to do this swap.

any help putting this swap together would be amazing, thank you.
Another thing i noticed is the black trim pannel with the hour buttons has an extra ( mode ) button with the 97 pannel, the connector that clips in is the same but the wires arn't the same colors going into each pin location.

gray = a
blue = b
white = c
orange = d
92-94 & 95-96 use the same plugs but different pinouts
97 & 98-00 use the same plugs but different pinouts
92-94 to 99-00
c13 to d13 - speed sensor input
c14 to c1 - speed sensor output
c15 to d14 - ground
