Hi,

Just wondering if anyone can help me out with a question I have. I have JDM clocks going into a UK car and they have an electrical KPH to MPH converter to go between the clock and plugs wiring.

I need to know which wire on the plugs side is the ECU Input or Output (can't remember now off hand which it is)? It is grey on the converter if anyone wondered. Any help would be appreciated.

Thanks.

 

Anyone?
