I want to install a ikeyFree Pro, a smart keyless entry system to my vehicle listed above EX model. I need to locate the lock and unlock wires near the fuse box, by the kick side panel or a place where it is easy to splice the wires. Any help would be appreciated.

Hi,

You have two choices. You can access the wires at either of the front door switches or at the smart junction box at the end of the dash.

The wires you are looking for are as follows:

1) Pink with a black tracer is to lock.

2) Yellow with a black tracer is to unlock.

I attached two pics below of the wiring schematic. Take a look and let us know if it helps.

Take care,

Joe
