Holley Projection Connectors
I got a used Holley Pro-jection (2bbl) system that I'm considering swapping into my 350 9C1 TBI.
However the injector connector pigtail is missing.
Does anyone know what the part number that 4 pin connector is?

Re: Holley Projection Connectors
If it's anything like the 2bbl replacement TBIs that Holley sold as "interchangeable, emissions-compliant" substitutes for the original TBIs, there is an "old" injector style and a "new" injector style.
If the injectors have a rounded, rubber cap over the top, they're the old style.
If the injectors have a molded plastic connector for a plug-in harness, they're the newer style. Holley has replacement harnesses. Not cheap!
If you have the newer-style injectors, look at a Holley harness p/n 534-167.

I had to order one of these for my 502-6 replacement TBI unit. I also ordered a pigtail to plug into the 4-wire molded plastic connector which would then splice into the OEM harness.

Re: Holley Projection Connectors
Thanks so much it is a newer style.
So you are saying that a pigtail like this

would work?
If I use this, I was going to drive it with megasquirt or an EBL ECU.
