What plug is this?

[FxMike]

There's a small plug that plugs into the side of our keyless ignition switch. What is that for? It recently broke off and was left dangling. It apparently might have broke when I replaced the dash. I did get a cel code after I replaced the dash. It ended up being for fuel temp sensor and fuel level sensor. I have an 04 fx45. I'll try to get pics.

The keyless ignition switch has a dust cover that springs closed, but can still allow the mechanical key to enter the ignition switch.
This what you're describing?

 

[FxMike]

No. This is what I'm describing. The white plug in the upper right. THe harness piece broke off. I plugged it in. You're looking from underneath, btw.

Possibly for the illuminated key hole? How may wires on the plug?

There was 4 metal prongs if I remember so 4? And no it's not for illumination that has a little bulb and housing on it towards the front.

Then, it gotta be the steering wheel lock unit. Wire color should be Blue Red, Red White, Red Black, & Yellow Black.

Does anybody have a diagram of our electrical system that includes our wiring harnesses?

I think NATS (Nissan Anti-Theft System) antenna amp has to do with communicating with the chip in the key when inserted.

 

[la_fx35]

Yep ^

Oh ok I got ya. Makes sense. So it basically tells the anti theft that I inserted the key to start the vehicle if my intelligent key system stopped working? So it's only semi-important. whew!
