2002 Saturn L200 remote start

Hi- I just installed a remote start in an 02' Saturn L200 and am having a problem w/ the airbag light staying on if the car is started with the RS and then the key is placed in the 'Run' position. If I turn the car off and start it with the key, the airbag light goes out. I am only powering the orange Accessory wire, and not the brown one. I was told to use a relay to supply +12vdc to both accessory wires. When I tried that, the "Service soon" light popped on. I think it's because the two accessory wires end up tied together in this configuration. After removing the relay and supplying power to just the orange wire again, I'm left with the original airbag light problem, and the "service soon" issue goes away. Any ideas? Also, does anyone know specifically where the horn wire is hiding? I can't seem to ring it out. Thanks in advance. -Tom

did you power up both ignitions? dei says to power up both acc and both ignitions. how did you hook up the relay?

Thanks for the horn info... Astrochart says......power up accs,#2 (brown) or the airbag light will stay ON..... When I power up access2(brown) the "service" light stays on. did you power up both ignitions? dei says to power up both acc and both ignitions. how did you hook up the relay? I did power up both ignitions. I'm using the RS access wire to power up access#1 (orange) and I'm also having this wire power the coil (85). I'm using constant 12vdc+ (from ignition harness) that will power access#2 (brown) upon closure. Could this be a situation where I need a diode to avoid backfeeding from the access#2 wire? This isn't the worst situation, but I'd love to have it working 100%. What could cause the "service" light to be coming on? Thank you everyone for your help so far. -Tom

I finally figured it out. There were several unrelated problems. The service light was being caused because I had the wrong wire at the ignition for key sense. Once I moved the wire to the proper key sense wire, I realized the wire I used only goes to ground during crank. I was already using Ignition3 to enable the PassMod module, so I ended up reversing these 2 wires and everything works great. Thanks for all your help. -Tom
