Welcome to the ZDriver forums.

You can download a copy of your cars Factory Service Manual from Xenon.

XenonS30

 

In the BE Body Electrical section, diagram BE-3 (4/33 in adobe) it shows the tach harness in B, G, BW, GW colors , there should be a connector under the dash with those colors, there are also lights that plug in too, unless it was cut out all that should be under the dash. on 13/33 it shows how to install the tachometer and speedometer.

 

Wow good job PredatorZ
