New Light Harness to Older Precedent How to power brake lights

[Blackdogracing]

I bought a 2007 Precedent that runs great but the head and tail lights didn't work. When I took the cart apart someone added a crazy amount of led lights under and around the cart. I removed all the extra lighting and tried to connect the normal lights and they had cutoff the taillight wiring. I tried splicing into the existing harness but still no lights. I had a harness for a newer Precedent which I installed and have lights and turn signals. The problem I have is the newer harness has the gray wire with the red plug behind the dash for brake light power but nothing to plug it into with the old harness. How do I get power to the brake lights using the newer harness?

Can I just run a 12 volt positive to the gray wire. Anyone ?

Duh, figured it out. The gray wire just adds the circuit to the key switch and is not the power for the brake lights. Splice the Blue and Green/White 12v wires together gets the power to the brake light if you don't care about having the circuit tied to the key.
