    Rated 4 out of 5 by from Painless Universal Wiring Harnes I purchased this wiring harnes for my 32 roadster. The labeling of each wire was outstanding. Layout the wires, and follow the labels. The reason I am not giving this a overall rating of outstanding is customer service. The connector for the steering and the harnes required a different adapter then the one supplied. Too get the right connector took two phones calls to Painless, no action, and one call to Jegs. Jegs got the job done for me. A special thanks to Jegs customer service.

    I have a Factory Five Racing Cobra MK 1 replica that is not fuel injected. Can this harness work?

    Asked by: bubba29
    Yes, as long as you have an keyed column, This universal harness might be a better option - https://www.jegs.com/i/JEGS-Performance-Products/555/10405/10002/-1
