Hi All,
I'm acquiring all of the various components to perform the carb to Holley EFI conversion on my car now. The two choices I found for the main wiring harness are their #558-104 Universal MPFI Main Harness and #558-105 Un-terminated Universal Main Harness. Clearly the universal MPFI harness would be the easiest, but I know that several of the connectors would not be needed, some of them would probably be too short like the O2 sensor, and some too long. This is, of course, less than ideal. Both harnesses are priced the same (way too much IMHO).
I'm leaning towards the un-terminated harness so I can eliminate unnecessary wires & connectors and optimize the lengths, but the price of their crimp tool 567-100 is steep. These connectors appear similar to Weatherpack and I have a crimper for these, but I don't know if this will work on these Holley pins. I also have an Amphenol crimp tool which crimps pretty small pins like these but I can't be sure if either of these will work with these Holley pins. If anyone has extra pins I could experiment with I would gladly buy some from you. If someone has a Holley crimp tool they no longer need I would be interested in that for sure.
I'm hoping someone here has been through this and can add their insight based on what worked for them. Any and all input is appreciated.
Thanks, CobraRGuy
