96 Mitsubishi Eclipse remote start

ok im helping a friend do an install in his eclipse and we are having troble getting the door sensor to work and trigger when the door is opened, and getting the remote start to work, just having troble with the door sensor from the start, it sets the bypass i believe for the door and shows that its open. and even when its closed it still dosent work correctly. and we cant get the remote start to even try to crank dosent even show up on the remote that its trying. but we arent totally sure what some wires need to be connected and what dont for the 96 to get the remore start working. any help would be nice
