20v Conversion - Using Original Clocks - Fuel Gauge

Hey guys

Just looking for some info, I know most of you's are using MS with 20v conversions, but I've got a full loom with chipped ECU & key, so I'll probably be using that.

I've been thinking about using the actual clocks in place of the original ones, but the only thing I can think of as being a problem is the fuel gauge, as the plug will probably be different for the loom and the signal settings from the fuel level sender will be different as well.

Does anyone know how to get around this?

Thanks
