Looking at the schematics, I see it (04 highlander) has a 2nd starter wire, I'm planning on installing an autopage rs-900. Do I need to connect the 2nd starter wire? I read somewhere srs light will turn on? If I dont connect it........ If I need to connect it,.....The rs-900 has a 2nd starter wire option but its a (-), do I use a relay to convert to + ?

Can I connect both vehicle starter wire to the primary starter wire on the autopage module?  (ie. 2 wires to one) Any harm?

I've done 2 remote starters in the past but never with a 2nd starter

Thanks in advance

Is there a difference between chris's method and this one?

85 (-) 2nd start output from rs900
86,30 constant fused 12v
87 2nd start wire on toyota

I'm not familar with relays and have only used them once or twice

Any help greatly appreciated
