How to install third-party keyless entry
 

I recently purchased since the driver-side lock cylinder on my 2007 base model no longer turns and it's a lot less expensive than the OEM part. However, I've never done any electrical work on my car before, so I'm not really sure where to start. I've removed the panels covering the fuse box and other wiring, including the ignition module. contains a picture of the included diagram, but without better knowledge of the Fit's wiring, it's not much help to me.

Doe $15 I doubt even if you got it working it would last very long. I expect there is no one on here that can understand those instructions. Bite the bullet and get original part.

Looks like you need to find white/green and white/blue wire according to this:

I used this site to wire up the keyless in my Civic and it was somewhat accurate. I still verified all my connections with a multimeter before hooking into them.

The locks are negative triggered so the module needs to send a (-) pulse to the door trigger.

I would throw that module away and get a better one IMO.
