Xk150:Fuel Sender Harness Route

I am trying to figure out the last 3 feet of routing of the harness to the fuel gauge. I have it from the fuel tank through the frame but not where is should go once out of the frame to the actual fuel gauge. Thanks

from memory there is a join in the wiring at the bulkhead on the right hand side via bullet connectors. these connections a re from the vague and are in the main loom. if you have the wiring diagrams from Covenrty auto components it should be clear. if not I could try and scan and send the relevant diagrams.
my car is a LHD 1958 150 fhc
