Outer Limits 4x4 Board

Gday guys. i'm trying to install a touch button immobiliser in my 60.

its a late 89 2h with turbo, issue i am having is i just cannot wire it for it to function correctly

the immobiliser is just a small hidden away push button controlled unit to press before turning key. is pretty much just a relay to hold a circuit open.

the fuel cut solenoid has 4 wires, white - has a really low voltage like less than 1volt . this is where i have it wired
red - has constant 12v,
yellow - unknown
green - unknown
all controlled somehow from the control unit relay

eg: i can get it to work for startup but then when i turn key off i have to press it again to turn it off.

what i think is happening is that the voltage is too low in that circuit and is not holding the relay in the immobiliser open?

also i know they have a electronic fuel cut relay in the kick panel , and was thinking that it should be wired somewhere before this? so that it shuts that on and off?

it just seems like such a simple thing to wire up but just cant get the bastard to work

here is the diagram from the unit


if anyone has any experience any help would be appreciated.

thanks

Rick
