that'll be it
there's 2 connectors there next to each other 1 bigger than the other.
both coolant temp sensors but i think one sends signal tot the ecu, then fans etc hence me asking if the fans were on permanently. which they would be if this one was unplugged.
the other i think just controls the gauge yeh, so just clean it up and plug it in right.
other than that awesome stuff mate - when you makin the mahoosiz trip down to jez then?
