I installed H4 headlights last year as an upgrade. The Lows worked fine but the 100w high beams burned out a ground I believe in the stock harness.

I'm installing a relayed headlight harness from Painless wiring and all is well except the highs don't work still. I think since that ground is bad there's not enough juice to switch the relay on.

With the high beams turned on, you can here a wire shorting somewhere near the pass. headlight, but I can't find the exact location.

Does anyone have a schematic or otherwise know where the ground for the high beams would route on a 93-97 Firebird?

 

Or is this a power wire issue? Do high/lows share the same ground?

I should mention the parking and fog lights work fine on low, but on high beam, they flicker in unison with the shorting/crackling sound. I think its a wire frying because you can smell it.
