wolfely

Need help, bought a 4.8 vortec/ 4L60E out of an 08 Savana and did not get the engine wiring harnass, nor the TCM, need both and am told that the harnass needs to be from an 08 or newer, anyone have one or at least any suggestions, this is going into my 57 Chev and I am setting it up as a daily driver, I know I can buy an after market for 750.00 but am trying to save a little for the rest of the big ticket stuff, tires, wheels, body panels etc, thanks in advance for any help
