I did mine by basically the same write up and I hooked the brake light power wire into the wire going to my brake box! I run the wire that was hot all the time from the fuse box and the ground wire under the dash so I only have one wire going out under the hood and with doing it this way it took a lot less wire for the job(unless you have a good source for free wire). I'm really happy I did the exhaust brake instead of gutting the EBPV for more power. I have seen a plug and play setup on Ebay in the past but it was alot cheaper for me to find my own parts for the job(sometimes I like a challenge).
