Guys, I need help fast. I'm moving and need my car running soon. I installed a custom LED gauge setup recently and everything has been fine until now. The car was running at 13.5v consistently and now it'd down to 9-11.4v when on. When off with the key on, it's 11.9-12v. I just pulled into my garage and it almost wouldn't start, it cranked really slow like a dead battery, and it kind of hesitated on acceleration. The battery and a lot are new and I fixed an initial wiring mistake by connecting the pink/black wire to the brown alt wire behind the gauges. I didn't keep the resistor from the bulb between the two and wonder if that caused damage to the regulator. I fixed that by soldering the bulb with resistor between them and then charged my battery, but it's still only running at 11'ish volts.
My questions are: There are two pink wires with black stripes on the wiring harness that I cut, how do I know which one is the right one to use?
The other wires, which connect the water, volts, cruise, etc that aren't being used now are just snipped. Do they need connected to grounds or the pink/black wire to close any loops?
It's weird because it ran fine for 700 miles after I put this car together and then it sat for a week. The last time out, it was night be the time I left for home so I had the lights on, and it ran down so low in voltage that it was almost ready to die. It went down to around 7v! I had to drive home with the lights turned off. When I did that, it would climb up to around 10v but nothing more. That was when I started looking over my wiring and learned about the resistor in the bulb.
I also switched the brown wire to the other pink/black wire hoping to see any change, but I did not. Here are pics for reference. The two wires I'm using are standing up straight in the second and third photos.
