    Have an intermittent problem with one of the fuel pumps not working. Found that tapping on the fuel pump relay,or in the general area on the electrical panel. Did the standard, pull the panel and solder any suspected connections. I believe the manual says the color of the wire coming from the harness out of the electrical panel is beige for the rh fuel pump and beige stripe black to the lh fuel pump.
    I dont show any beige wires coming from the panel. Supposidely the wires are on the y harness junction?
    Any and all help will be appreciated. . Thanks

    Sometimes "beige" is actually more brownish appearing -- see jpeg for the side-by-side location in the "y" connector (unplug the upper "x" connector first):

    No trouble -- I fear every TR will need intervention in this area eventually.

    Can you post a jpeg of your "bad" condition?
