2003 tacoma double cab v6 4wd auto ***not factory equipped w/ tow pkg(has orange fan blade pulley)***

i recently installed the factory tow hitch and wiring harness to my truck. problem is the "converter" that came with the wiring harness kit says to be installed behind drivers rear seat againt the back panel. when the back panel cover is reinstalled the carpet sticks out and does not look good. is there a better location for the "converter" than the instructions call for or is there a different molded back panel cover that better fits the converter???
