mazda b2300 wiring harness

i was wondering if anybody knew where i could get a wiring harness for my 94 mazda b2300? is there any companies out there that make the harness for certain trucks? i was wondering what i am goin to have to do to rewire the truck since its fuel injected and has all the plugs on the motor. any help would be great.

pain less makes one pretty much one for everything
