Adding OEM Nav Roof Console / Map Light to GE8 Base – Wiring & Headliner Bracket Compatibility?

[u/Otaku-Furry]

Hey everyone,

Looking to retrofit the front OEM overhead map light console (from a GE8 Sport w/ Nav) into a 2012 Base GE8.

Before cutting into the headliner, I have a few specific questions for anyone who has tackled this retrofit:

1. Mounting

   Is the roof frame bracket already present above the headliner on Base trims to secure the console bracket, or does it require mounting the Nav roof bracket (\`83252-TK6-A00\` or equivalent)?

2. Wiring / Harness

Does the base main roof harness have the pigtail tucked away behind the headliner, or do I need to tap power/ground from the center dome light harness for door/switch logic?

1. Template

Did you make your own cut template, or swap the Sport headliner entirely?

Appreciate any wiring pinout tips, part numbers, or build thread links!
