Need:
1.) Correct MFS (CAD code/blue(?) plug)
2.) 'Oncoming light' detector module @ inside mirror (controls dimming) w/mount (suggest perhaps changing to correct mirror assembly)
3.) Daylight detector module inside top of dash, driver side (turns lights on/off @ dusk/dawn)
4.) Dual rotary switch module (mounts right side of headlight switch)
5.) Dash bezel with (nearly) square hole to mount #4 (or cut out the one you have)
I can see adding all of these easy enough, except for maybe #3 - I don't recall if it is reachable when the cluster is pulled.
The shared 10 amp fuse is in cavity #19, under the dash, so that should be ready to go.
There is speculation that cornering lamps came as part of the optional 'autolamp group' - your choice to add them if the car doesn't already have a pair.
I'm guessing that the harness is ready - if not, I'd give it up.
