As the title says I used this to do the high speed blower motor mod in my 92 Dodge D350. Worked Perfect, easy and clean install. It costs a little more but it beats sourcing parts and making your own.

This is a great product. Wasted alot of time trying to find the components to run an electric fan upgrade.Heard about Painless, problem solved.

I have a 2012 f350 that had wires corroded off the fuse box ECM relay. I used this harness to relocate the 70 amp relay. Everything works fine now. A longer ground would have been helpful but it was not used for a fan application.
