If the Ranger's use the same 6 pin(5 used) connector then all you would have to do is rearrange the pins to match those of the Toyota, that is all I had to do to use these Mazda taillights on my flatbed.[Linked Image]

However, you would will still have to convert the Toy 5 wire harness to work with the Ford's 4 wire, not a big deal, just something that needs to be addressed if he wants to make the conversion a bolt-on/plug-&-play set-up.

More than tread lightly. Leave it like you were never there, nor anyone else.
