i am con fuse about thes wires the data wires RX and TX what do you use that for and the IMO and IMI wires again how you use them or hook them up can some one help out

The DATA RX and TX are for your bypass module. When you insert your key the cylinder around the Ignition cylinder sends a signal to the ECM that tells it that the proper key is inserted and the car is allowed to start. When you remote start the car you have to simulate this with a bypass module. After installing the bypass, you program it with the factory keys to replicate the signal that would otherwise be provided by the key going into the ignition cylinder. The RX and TX wires allow the signal to be sent from the bypass to the ECM to allow the car to start.
