Hi phunk,
I've been searching the service manual for the right wire to hijack. Might you point me in the right direction if you've already figured it out?
I found more than one potential STOP LAMP SWITCH:
Terminal 122 of ECM connector M107
Terminal 116 of BCM connector M123
Terminal 118 of BCM connector M123
I found the STOP LIGHT FUSE number 7 in the driver side fuse box, but failed to trace it to it to one of the above terminals. Ultimately I'd like to understand
why interrupting the brake wire keeps the brake light working while the fuse won't. The manual's wiring diagrams are hard to read
