    I'm with above.
    Usually heatshrink butt connectors will fix most jobs.

    If you post a picture of said connector. I should have one to disassemble, and post information about it's disassembly.

    i watched a few videos on youtube , the best came from speed academy it shows what tool to use but there is two versions of EV1 connectors, i couldn't do it right no matter how i tried...best of luck to you. i ended up cutting the ends up to splice to EV6 connector for a different set of injectors...

    Anyone know about a 4 7 swap and whether or not I can just switch the pins in the wiring harness for the injectors when I switch the plug wires? If this is possible, and it should be, does anyone know how to depin the Delphi connector?

    Don't use the # sign. It turns it into forum links.

    You can put a space between it like this: # 1234

    I have a small block Chevy with a cam ground for a 4/7 swap. Can I switch the pins on the injector harness between Visitor Messages#7 and#4 and vise versa, which would be left 4 and right 2 injector wire to accomplish this when I swap the spark plug wires from Visitor Messages#7 to Groups Groups Groups and vice versa? Has anyone done this or should I have any concerns about this firing order modification?

    Thanks for this excellent diagram. I was stuck and not sure of the layout. I am used to 1,3,5,7 and 2,4,6,8.

    Pro-Flo 4 Fuel Injector Wiring Harness Layout

    There's been some confusion as to how the Pro-Flo 4 fuel injector harness gets laid out on different engines. In order to have a single fuel injector wiring harness that fits all engines regardless of make or cylinder order, the harness has been designed to have call outs for left or right bank cylinders and numbered 1-4 from front to back. Left bank injectors are labeled L1, L2, L3 & L4 and right bank cylinders are labeled R1, R2, R3 & R4. Left and right banks are determined by viewing the engine from the back - see image below.
