ok so my board is built now time to put it in now when i wire it in do splice it into the the sensors and leave the stock ecu hooked up or do i run it straight from the ms to the sensor also where do i get my tach signal from and ...basically is there an easy diagram for where to hook everything up onthe rotary let me know please thank you

 

The way I did it was run my owne wires. If you can find a pinout from the stock computer you might be able to use the factory harness. To me that is a bunch of crap. You are going to get your tach signal from the yellow wire with the blue tracer on the trailing signal plug and that will go to the same color wire on the back of the gauge cluster.
