Low Volt Relay, Neutral Pos Sensor

For Viper 791XV on MY04 Impreza The ECU's neutral position provides: NONE during neutral GROUND when in gear The solution that I've found that I like and works on my situation where I sometime put into 1st gear when I park on a hilly road. Connecting the brain's neutral sensor to ground at all time (requires ground to be able to remote start) Then...Neutral Pos sensor from ECU, hook up to relay to provide positive then connect that + to brake light switch so that the alarm brain will not remote start because the brake is pressed. The problem is that ECU's neutral pos wire can't even trigger 30A Bosch relay = I need a low wattage relay. I'm not familiar w/ low wattage relay. Which one should I get and where to get it? Part # would be helpful.... I also need to put a diode from the + output of the relay to the brake light switch so that it won't turn on the brake lights when the car is in gear. I tried using the 1A diode for testing and it became soo hot.. Do you know which diode I should use and where to get it to "oneway" 12Volt positive drawing about 10A.. Any help would be great... Thank You, David

Why are you trying to use a low voltage relay??   You are just asking to burn out the neutral wire. I already told you how to do this. https://www.the12volt.com/installbay/forum_posts.asp?tid=67714&KW=salaki Neutral wire (with diode) to hood pin of 791.....parking brake wire of car to neutral input (BLACK/ white) of 791. This method works best. No complicated relays to go bad. Stop trying to make it complicated.
