if any one know how to get around buying a new harness please tell me. there has to be a way (i hope) to splice the tpi harness to mine and get rid of what i dont need from the tbi set up. im on a tight budget and i pretty much tapped out on a cam, headers, air foil. and adj fuel pressure regulator. hell i even scrapped the 3 inch flowmater cat back from it, and cat co cat. to about an hour with the mig but i got it. i dont need a kit with a ecm cause i have one from the cam same goes for the harness. im cought in a spider wed of wires. please help. thanks. the stangstomper

 

You basically have two choices:

1) Get the wiring schematics for both systems, splice away (I have a bud who did that).

2) Find a used harness at the boneyard or on the thirdgen.org classifieds.
