66 rear axle/differential

Asked by Jul 22, 2011 at 04:56 AM about the 1966 Mercury Park Lane

Question type: Maintenance & Repair

Hi all.
A friend of mine asked me this:
Why is two elictrical wires going into the differential? (He only has the rear axle, not the car)
I was dumbfounded, but took a couple of wild guesses:
Is it a transmitter to something? Is it an electrical sort of hill-holder?
I've searched the net to my best, but came up with nothing.
That's why I ask all of you: What are they for?
Any help will be deeply appreciated :o)
Thanks in advance

Terkel, It's possible that the rear contains an Eaton ELocker Diff. Of coarse that's not original equipment for the car or the rear....but it would definately explain why it has two wires hanging from it. Riff

Hi Riff. That may be it. Thanks a lot :). I've never heard of those before, but I read up on them after your post. I think its unlikely, it's an Elocker - why would anyone put that in a Mercury? But it is absolutely a possibility. Thanks again. Kind regards Terkel
