Holley EFI harness adjustment

67Dart273...I was considering cutting and splicing. I'm not sure if the connectors they used are metripac, or Delphi?
Sorry don't remember. The housefire has changed a LOT of what I thought I had. As I said, if you go over to or join the Holley Forum, somewhere on there is a list of alternative supply source for the connectors---much cheaper than Holley. I actually bought some and was going to build my own. Sometimes you can find random lengths of various colored wire on ebay. I've also bought things like long (10ft, etc) printer and other multiwire computer cables from thrift stores for that purpose
