Anybody know what the colour code of the wire that shows the speedometer and what not, thanks

I'm not really certain as to what you are asking for but here'* some info:
90 is DK GRN/WHI.
93 is DK GRN
97 is DK GRN

This is the color of the wire between the ECM or PCM to the speedometer. I assuming that you are asking about a 95 because of your username. If so, someone with a 95 manual should confirm the color.

Can you give us some more detail?

im trying to hook up my vehicle dynamics, to my car, i t-ed into the dkgrn and white striped, not working must be the wrong wire?

Since both 93 and 97 are DK GRN, that would be my guess. I probably should have mentioned that above. The easiest place to tap into that circuit would be right at the ECM. the problem is, there'* probably going to be 4 or more wires the same color. Best bet would be to wait for a 95 FSM owner to chime in and give the correct connector & cavity for that wire.
