Help Identifing Wiring Harness?

[OpieNoTool]

I need help identifing A wiring harness. I bought the harness acouple years ago from a member on here for a 5 ton truck i was re-doing but it din't work out. The more i look at it the more it looks to fit a M35a2 but im not sure because the NSN numbers dont match. Ive searched all over and everything i find just says Branched Harness. Any help would be apreciated.

The NSN # 2590-00-911-5653
