Hello i have a 1990 Honda EF DX and i bought a 1991 SIR ef cluster. can anyone link me to diagrams to show where to put the wires from the DX harness to the new SIR cluster so it can work properly???? i finished my swap and its the last thing i need thank you ):

 

not sure there is anything out there, I just traced the back of the board and matched up functionality. not rocket science, these old clusters are really easy to trace, there is no logic in them.
