WQ Fiesta XR4 Diagnostics/OBD2 Reverse Engineering

[Luke Plaizier]

So all ex-fiesta bits? nice.

The roof loom will be the only bit specific to the fiesta. Everything else can also be found in Focus/Mondeo/Transit - Switch, Sensor, Sensor Covers etc. The headlight switch with everything is one step above the Fiesta-with-auto-lights. The only real difference is that it includes a dimmer switch dial for the interior ambient lights, but it has a slightly different pinout at the back, so the dimming feature won't work in the Fiesta without some minor changes. There's a write-up about getting that to work at https://fiesta-mk6.pl/
