help swapping a 5 speed for an auto

[bbullsj]

i hav an 89 supra turbo. i'm looking to swap out the auto tranny for a 5 speed but i ran into a snag. i need a new wiring harness b/c mine is falling apart and so i want to just replace it so i don't have to worry about any wiring problems down the road. i will also re pulling the engine and rebuilding when doing the tranny swap. my question is: should i get a harness for an auto tranny or a 5 speed? the car also has ABS and i'm sure that makes a harness a little more tricky to find. a friend suggested a company called Painless Wiring. he said they have a lot of varities of harness. i haven't checked into it yet but if anyone also knows where a good place to get a harness would be that would be a great help. i'm looking for new or used, it just need to work. the question is for an auto or 5 speed though.
