Hey guys I recently bought a 97 5.2 4x4 auto and a 98 2wd 3.9. I swapped fenders doors hood and bed. Now if I step on the brake pedal the high beam indicator and right turn signal light up on instrument panel and the window switches lock the doors and wont roll up. I've triple checked ground wires under the hood and can't figure out wth is happening. Only thing ive found to be different is the horn. The 98 has two and the 97 had one. I haven't hooked the horn up because of single wire versus two wire set up.

 

Moved to the correct section.

 

Check for a badly pinched/shorted wiring harness

 

ground fault.
