I replaced both of my harness pigtails.They usally break when you try to disconnect them. Be careful that you don't break the oil pressure sensor when you take the intake off.

I bought a new harness from the dealer when I did mine cause the orignal was falling apart. Make sure to torque the sensor to 15 ftlb and no more or you'll get false knock.

Oh and while you are under there you should TSB for them. I don't remember the number but they also say to make a silicone water dam in the shape of a horse shoe around it after installing it, 3/8 inch wide and 1/4 inch high with the open end of the horse shoe facing the rear of the engine. Also to remove and disgard the foam from under the intake manifold before installing it.

ah, thanks for the tips 
since my stock intake is 11+ yrs old, any reason to replace the intake gasket?
I work at Carquest, so parts are cheap for me
