It is my understanding that the "backwards" lines were used on the 3/4T trucks. Their 1/2T little brothers used the standard front reservoir to the front brakes. You didn't mention which reservoir you purchased.
Need some more information. But generally I would say it's backwards. You seem to be missing the proportioning valve that also indicates if you lost fluid on half the brakes. (Never mind, I see it attached at the firewall now I looked closer).

Should be a great upgrade.
