Where to get a aftermarket wireing harness?

I gotta 1987 Mazda B2200, the wireing harness is pretty torn up and I wanna rip it ALL out and get a new one. But not sure where to order one at I found sites online for universal ones but I am not sure which one to get, any help would be great! Thanks!

like which one?

painless is waaaaaaaaaaaaaaaaaaaaay to expensive, try EZ wire.

painless is worth every penny if youve ever put one in. if you want a stock harness, i could fish the one out of a parts truck i have.
