Outer Limits 4x4 Board

as the title says i need the wiring diagram for one of these tachos the wire colour code is red, white, green and black

a fair few posts have been put up in regards to tachos but i would say they are as follows:
RED: switchable 12v
WHITE: Park lights/dash lights
GREEN: Coil - Positive side
Black: Earth

hope that helps
