Can't find any specifically for trucks, do Mustangs have the same plugs? I'll probably just extend the wires manually, but its pretty tempting to just plug 'em in....

 

call around. i do believe, however, that the O2 sensor extensions are the same for all fords. when i got mine for my longtubes, they were labeled "ford o2 sensor extensions." honestly, i also would rather plug them in than extend them manually. however, the sensor extensions i got were 18'', and i needed only about 12'', so be sure to tie off excess wiring so that it does not get burnt up by exhaust components.
