The nitrous works flawlessly now. We eliminated all the past electrical misery we have had since putting the car together by installing a complete wiring harness from Spaghetti Menders http://www.racewiring.com . We were using a two stage timer along with a rack of relays. This kit uses a Digiset timer that is so simple to use, it's a crime. Check out their web site and you'll be amazed at the simplicity. I removed a total of 17lbs of old wiring, and replaced it with the 6lbs that his kit weighs. Using that kit also allowed me to remove the second battery and cables that we had in there, another 50lbs gone in an instant.
