If the wiring is there in your car should be a straight swap but if not you will have to run wires in for the rev counter from the ecu iirc

.....i want to change the clocks on my corsa to the clocks with a rev counter. I'm just wondering if i got a clock with a rev counter in will it just be a straight swap. I have an electric clock at the minute so if i find an electric clock will it just be a case of pswapping them over or not?
