I know i probably spelled it wrong .Im trying to replace the old abs in my 91 with the 96 xj booster and other associated parts of the 96 including the Proportiong valve. My question is which oulet is to which brake line on the valve .. Am I safe to assume that the one that comes out of the rear toward the firewall is the back brake line and the other two that run from the underside of the valve to the driver and passenger front wheels wheels? Thanks in advance for any info.
