One wire is brown, the other brown with white trace.
Is the brown for the temp warning light and the brown/white the switched earth for the fan relay?? as its this that tells fan when to come on..?
That is all. Thanks.
radiator temp. sensor wires

i never new there was a water temp warning lighttheres just the gauge? which is the blue wire. the rad/fan wiring is a simple power circuit which goes.
power - thermostat switch - fan - earth
what he said/\
well the digi dash does flash a warning light when its boiling over.. but nah ur right its prob just an in and an out. im trying to connect the switched earth for fan relay to mbe output..

that warning light is probably internally connected like fuel lights.Originally Posted by peester
i assume you set the temp you want your fan to come on within the mbe software? making the fan switch redundant? if so then use the power feed to the fan switch but connect it directly to the fan, cutting the fan switch out basically. then the other side just connects to your mbe, i would assume anyway, thats what makes the most sense
all the fan switchon the rad does is connects those 2 wires whe it hits temp. bridge the plug and the fan runs constant. the didgi tem guage connects liek any other, they flash due to an inbuilt chip that when a certain voltage is hit it triggers and makes it flash as a warning.
well i think i got my head around it.. ive just connected the brown to the ecu output. see what happens.

sorted this the other week. In the process of doing a how to guide
