2003 Toyota Camry, Autostart

I have put an Autostart model# 1424 into a 2003 Toyota Camry. The problem is that whenever it gets cold, the vehicle won't turn over. I tried reprogramming the tach while pressing the gas to increase the RPM slightly to simulate a cold weather start. Still refuses to start. Is there maybe a 2nd starter wire needed only for cold weather start? I got the tach wire from a grey connector at the right side of the steering column. any help would be appreciated

Your car has 2 starter wires that need to be hooked up in order to allow cold weather starts especially.  Use a relay to power the second starter wire if your unit does not have a second starter output. the wires you are looking for should be a black w/white and a black w / YELLOW(thin gauge wire) I hope this helps!! Dont just jump the cars 2 starter wires together to the RS. Use a relay and do it right!!WesMan

That's the same tach wire I use. I haven't had problems, but I've heard of people in colder areas getting the occasional comeback. And yes, the Camry certainly has two starter wires--- the thick BLACK/ white, and the thin BLACK / YELLOW.....but I don't think the car would even start at all if you didn't get both of them.

the car will start on warmer days but o cold days, that second starter wire feeds some kind of temp. sensor which i guess adjusts the fuel or the timing for cold the weather starts.WesMan

 How do you wire up the relay? What wires go where, I've got an 06 Solara thought i had it wred correctly but it still won't start, it gets right to the final point but wont send start signal.

Thanks worked great, needed to have second starter wired up
