    I've purchased a Terminator EFI system (550-406K) with complete fuel system back in '16 during the Christmas holiday. Fast-forward to fall of 2019 and I'm ready to install this into my ride. I purchased a Holley dual sync distributor and I'm somewhat confused with the instructions to run CNP. The instructions show the LSx BLACK/YELLOW even & odd wires to be spliced together, but it literally doesn't say to connect them to the "EST Ground Out" B14 terminal in the J1B connector. The B14 terminal has a black wire in it already and it's connected to the black wires on the CAN connectors. Am I supposed to splice the LSx CNP black/yellow odd and even leads to the J1B B14 black terminal lead? My Holley 558-307 CNP main harness has the two black wires with terminal crimped. I'd have to cut them and attach them to the existing cable in B14.

    Just follow the wiring diagram in the Holley 558-307 CNP main harness instructions (LINK), even if there's already a wire in B14-J1B (EST Ground Out).
    May God's grace bless you in the Lord Jesus Christ.

    OK, I have to splice into the existing B14 terminal. It shows that on the diagram, but it didn't say so in written word. That's what I was unsure about. Thanks for the help!
