I've got a spec R header tank on my saph which must of been for a 3 door as it has the hole for the level sensor, I've got hold of a level sensor and want to wire it up to a warning light on the dash, problem is I cant sus out how to do it.
When the level is ok the switch is made so its not as simple as just wiring a bulb in the circuit as it would be on all the time, the other problem is it wouldnt be that easy as the switch will not pass enough current to light the bulb anyway.
Looking at the wiring diagram the wiring goes to a module, does anyone have any idea what I can do to get it to work, I dont mind a bit of soldering etc, I've had a look inside a couple of warning modules I've got lying around and there is just a microchip in there so I'm thinking I'm screwed for wiring this up?
