64 DART 4 way flasher wiring

Thanks Dan for that useful information. Now what to do sell it and try to find the correct one not likely .I checked parts voice with the correct # for 64 and the vendor wants 350 . I do have another 64 parts car maybe I could take the wire ends off it and try to figure how to wire it onto the wiring I bought that way I wont have to cut wires on the car. I do have the 4 prong switch frim a 65 Dart. Dosent a flasher have to be installed in there somewhere. I think Im going to need a wiring diagram.

And I wonder if 64 65 and maybe 66 take the same wiring connectors
