Proportioning valve

Hi, I have a proportioning valve from a 79 Ford F100 and am not sure which end is which. there is a nut on one end for adjusting and am not sure which end it goes (front or rear). I am assuming the nut end is for the rear brakes. I just don't want to install and re-install. If anyone knows I would appreciate any advice. It might be called a combination valve also, it does have a switch in the middle top portion which I believe is a low fluid warning switch but not sure on that either. Thanks
