Let's have a look into the cockpit of the Bf 110 F-Series.
Left side:

The housing for the prop pitch lever and switches is now standard. Above them the 4-switch-fuse-panel for the fuel pumps(since the belly tank[Dackelbauchtank] was deleted, the panel changed from 7 switches to 4).
There is an additional knob on the right throttle lever, to activate the landing light when pressed.
Front panel:

For better instrument flight the panel was changed. Also the 2 control lamps, above the variometer(k), for the "Rüstsatz M1" 2x MG151/20 + 200 ammunition under the belly are already installed. 2x MG 151 can be fitted instead of the 2x MG 151/20.
At the top right of the variometer you see the "Drehschauzeichen" ( turn-view-sign? ) which shows the working of the de-icing-system of the armored glass.
See the pilots main-fuse-panel on the right side behind the compass, should be in all C-to-G-series. Additional UV-lamps(n) are installed for night flights.
This cockpit has the ZVK-FF ammunition-counter for the MG-FF/M installed.
The spare-parts-catalog from 15. June 1942 indicates a change in the armament from 2x MG-FF/M to 2x MG 151/20 with 350 rounds in thr right MG and 400 rounds in the left.
In case the MG 151/20 are installed, the SZKK 2 (Fl.47317) ammunition-counter should be installed in the panel.
This modification is from outside only distinguishable from the missing openings in front of the ETC 500/IXb (bomb rack).
OK, back to the cockpit.
Right side:

No big changes in the right hand panel (even it is a new panel...).
Left of the cockpit-light-poti(1) you find the turning-switch for the "Roland-Anlage" (only F-4) and it's control lamp below (also "Drehschauzeichen").
In the F-2 you might find the same turning switch and lamp, but with an additional lamp in front of the switch. Then additional position lights (zusätzliche Kennlichter) are added to the fuselage.
In front of those turning switch I guess the switch and the 2 control lamps for checking tire pressure.
You read right, the F-series has an electric tire-pressure-control.
The manual states that there are 2 control lights(one for each tire) in the cockpit and those are the only one I can find and have no real description for them, so I can only guess.
Engine instruments:

The only change here is from the double-oil-temp-gauge (oil-temp-in/oil-temp-out) to a single-oil-temp-gauge(oil-temp-in).
Good to see the mech. prop-pitch-indicator ( which is missing in CloD ).
And now a picture from the spare-parts-list, regarding the instrument panel in the cockpit.
