    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.
