No offense as it's unclear but you should find an installer if you're not sure where the wires go.
Your question provided no details on what it is you're asking for other than pin numbers.
CAN2 is to connect to the ECU as noted in the pinout.

There are other wire diagrams in the forum if you look.
Yes many have tried the Holley ecu
