I just purchased an '03 LX. It came with power door locks, but no keyless entry. I purchased an IC Dynamics Model 6RTA Remote Keyless Entry System from J.C. Whitney hoping that I could install it myself.
Here are scans of the instruction sheet. I'm still a little confused though. In the 3rd attachment, I have circled the section that states "Switch wires marked with an arrow pointer require connection to 10 wire harness". Does this mean that they should only be attached to the 10 wire harness (marked #2 in the diagram) or should they also be attached to the wires going to the door lock relay module (marked #1 in the diagram)?
