I am confused about installing the bee r rev limiter.

I bought a used unit with no instructions and even if it did come with instructions its all in japanese.

I need to know exactly how to hook it up into an OBD1 integra or civic since its basically the same.

I have tried connecting

Green - A 25 pin out (IGP1)
Red - to ignition source (accessory)
White - Hand brake
Black - Ground
Yellow - Confirmed tach signal



I have seen some other diagrams where you have to cut a pin out and tap another pin into the ecu. Am i missing something here?

Please all those who have the Bee R rev limiters installed please help a brotha out.

Thanks!
