Not sure if this is the right forum however I have an interesting question. How does the temp gauge in any falcon get it's voltage, from the ECU or direct from the ECT? I need to connect up the temp gauge on the muzzie but can't find in any of the diagrams, except the efi one, where the ect wiring goes. I have probed pin 38 on the ecu to get the voltage going into the ecu but unsure if I can just run the gauge off that wire ie will it screw up the correct voltage going into the ecu?

any ideas?

ok have since found out that this info is sent to the instrument cluster via the data output link. Anyone know how this info a sent or how it can be used?
