does anyone know whether the single wire from the temp sender goes straight to the temp gauge or does it go through something else first? mine is driving me crazy, one minute it reads 0 the next it's hot off the chart, then after a minute or two, it'll read 0 again and just repeat itself...... help

does anyone have the wiring diagram for the escos? the one I have is for the sierra, and the ecu multiplug wiring is different, anyone please?

Straight to temp guage from temp sender, NOT CTS though of course as this is ecu feed.

that's what I thought, I've rewired it and connect it to pin 3 of the multiplug on the back of the tacho, but still no use
