shutting down sensors for rs

trying to shut down a sensor for when rs.

86= fused 12v constant

85= ground while on rs from rs unit

87= not used

87a= to one side of the power wire to the sensor,brain side

30= to the other side of the power wire of the sensor,sensor side

checked the output of 30 and i dont have 12v, reversed the wires and still no 12v output. the ground output from the rs works fine. any ideas? in other words theres no current flowing through 87a to 30 when the rs is off.

what do you think?

85= ground at all times

86= 12v in the run position only, from rs or car.

30= one side of power wire to the sensor, brain side.

87a=other side of power wire to the sensor, sensor side.

still cant figure out why the above diagram wont work. ideas anyone?

you wont have anything on 30 when triggered.....cause theres nothing on 87......you are just "opening" the wire with your relay set up as you have it listed.     

87= not used

If you want 12v at 30 when triggered...you need 12 v at 87

Are you using one relay per sensor or just one for all three ? Also what do you mean by shutting down power on the RS ? Or did you mean shutting down power DURING remote start ? I've done this before on a system and I wired each sensor separately while breaking the wire like a starter disable relay configuration.

im using one relay to interupt power to both sensors. using the ground when on rs from the rs unit doesnt shut them down. thats why im trying to use th acc. wire from the car to trigger the relay open when it receives 12v. that way when the rs starts the relay will be open and the sensors wont trigger. would i need to use a diode like on the staret kill diagram?

85=ground at all times

86=12volts on run only from acc wire

30=one side from power wire to the sensors

87a=other side of the power wire to the sensors
