frame rail harness for fuel tank?

I have a 1990 wrangler (4.2 ) that I am converting to fuel injection.(1992 4.0 donor) I replaced the sending unit in the tank with the "1992" donor (electric fuel pump)
I have replaced the original 1990 under hood wiring with the 1992, and the under dash, and body tub wiring from the 92. my question is this, there seems to be no connection for the fuel tank dropping out of the tub harness between the tail light connections, I have done a bit of research and found there is a harness that runs along the frame rail from the engine harness to the fuel tank along side with the fuel lines. I am having a hard time finding this harness as everyone says it does not exsist.
