Willys Forum / Re: Seeking part: needing 1953 Willys Aero Eagle overdrive relay switch
« on: June 06, 2024, 08:42:32 AM »All Borg Warner R-10 and R-11 overdrives work the same. Some car mfgrs. wired theirs a bit differently. If you can't fix yours you can use more common Ford parts. A good Borg Warner wiring diagram is on Garage Tech With Andy Rundle site. Be aware that overdrive electrical parts are made of precious metals and priced as such. Tom.Another option would be a Studebaker overdrive relay which may be more readily available. The Stude relays look like the picture that Fid posted, as far as the terminals. Be cautioned that Stude relays were made in both 6volt and 12volt versions. Up thru 1955 will be 6volt; 1956 and up will be 12volt.
