@Campyman Where is the extra wire for rear license plate light?
I just installed the XTC kit. Excellent quality! Good instructions, but not very thorough. Tips: run the XTC wires to the rear lights alongside the OEM wires to the rear lights. Zip tie the XTC wire to the OEM wire every time the OEM wire is attached to something else (frame, harness, etc.). Also, the wide 4-pin rear light connector is too large to fit through the hole in the firewall where the grommet is, so I had to shave down the plastic housing on the wire connector and tape it back up again. Not a big deal, but I wasn't planning on having to damage their product just to install it.
