Lol. You screwed up is what you did. Lol.
Check your fuses.

 

Well this is a new one.

 

Seems like you created a back flow of energy into the PCM. You might need to remove the PDC and see if something arched over to another plug. It is possible that you could have fried your PCM but I don't think so yet.

Going off the electrical schematics 8W-42-18 in the 2002 service manual there is a 10 AMP fuse in the Run/Start in the # 21 slot. Look in the fuse panel inside the dash.

 

hydrashocker thanks I check them now don't think I fried anything I will let know as soon as I ck is it the same on a 2000 4.7 4x4

 

Yes. Thanks Hydrashocker.
Because I never said anything about checking your fuses.
Lol.
