Need wiring diagram for fuel pump connector (regina) 700 1991

A year ago I had an intermittent start problem , the only fuel intank pump , (regina syatem ), would not function. I thought I fixed it by paralleling the pink 12v wire from the no. 11 fuse block back to the connector located by the left rear panel in the trunk ( next to the antenna motor ) I thought there was a break in that wire so rather than trying to find it I just paralled with another piece of wire. Well the intermittent start problem is reoccuring which leads me to think that the fix that I did was not the solution. I followed a test procedure given to me by RSTARKIE and I got as far as connecting terminal 1 to terminal 2 of the harness , the bigger pink wire and smaller white wire , (to the fuse box , not to the pump )to see if there was battery voltage while cranking. Well I did not get that so what I did then was test for voltage at the pink wire and GROUND of the car and I did get battery voltage while cranking . This leads me to think that the problem is with the small white wire , I believe its the no. 1 ,although I am not sure as I cant remember now but in any case does someone has the wiring diagram to tell me where that white wire goes ? Is it back to the relay ?Further on in the procedure calls for testing the fuel pump resistance and that tested OK.. thanks

    I know next to nothing about Regina system. But, have you jumpered the fuel pump relay per the FAQs? There can be other reasons why no voltage to the pump.

        OK ..here is a follow up...I did as the FAQs , thanks Aleekat )suggested which is to jump from fuse 1 to fuse 11 ( approprite fuse positions )..pump did not work. I went back to the fuel pump connector located in the trunk and pushed/wiggle the wiring in the connectors . I then did the fuse jump procedure and the pump works. I then reinstalled the the two fuses into the no. 1 and 11 slots and turned the ignition on without starting and heard the pump priming.I then had a successful start...I think I am going to retrofit the connector . there is evidence (Discoloration )of heating at the connector especially the pink wire . Maybe that was the problem all along yet I am still curios as to where the four wires go. I know pink is the "hot" wire and black ..perhaps ground but the brown and white-gray ? Anybody knows ?..Thanks

          The brown and white/gray in the trunk are the fuel level sensor leads

          Those other wires may be the fuel gauge/low fuel warning light.
