We can build you a new 99-02 harness.

All you'll have to do is get a throttle body with an iac/tps and it'll work.

If not, get yourself a 02 truck harness, it'll be setup for a dbc system.

You can also convert your '03 harness to dbc, simply use the etc wires as the iac/tps and use an 02 pcm.

i have a spare intake with cable tb and i think i can find the plugs a salvage yard for near nothing .now will the stock pcm work or will i need and 411.

411. NP can build you a nice harness which will take a lot of the guesswork out.
