1994 pathfinder remote starter

Hello All,

Perhaps someone can help me. I have installed a remote starter and everything works fine of course except when its cold. The instructions I have found have shown me their is a second starter wire needing to be connected to the output on the starter output on the brain. I originally connected this to the starter output from the ignition switch and same problem. If someone could help me locate the second starter wire and if it is indeed the same colour BLACK / YELLOW. Any info is appreciated. -20'C in Canada right now and no way the truck will start with the remote. Everything else works on the remote start except this second starter wire.

Thanks
