Best Controls to use on Steering Wheel

[Moon]

My steering wheel is pretty simple but besides the steering, pedals, and shifter, what controls should I use on my steering wheel? What are the most useful functions in this game that you always need?

My steering wheel is basically just a PlayStation controller with pedals
It has a D-Pad and 4 shape buttons, triangle, circle, square, and x.
It also has R2 L2 and R3 L3 buttons if that helps

I stopped with all that a yr ago and now use voiceattack on all my games. Buttons seem lame now

What I have mine set to on my g920 is: DPad up - lights, DPad down Wipers, DPad left - engine brake decrease, DPad right - engine brake increase. Button 8 (looks like 2 squares) - engine brake, LSB button (kind of left bumper) - engine brake toggle, X button - high beams, Y button -cruise control resume, B button - activate, A button - Cruise control decrease, Button 7 (looks like 3 lines) - Cruise control increase, RSB (kind of right bumper) - Cruise control set, Round button in center that has an X on it - engine start and stop, Right paddle - right turn indicator, left paddle - left turn indicator.
Those are the buttons that I tend to use most. I use a skrs type shift knob for my range and splitter for manual transmission. Before I started using my shift knob, though, I left out engine brake increase and decrease so I had the range and splitter on my wheel.

" functions in this game that you always need?"
I have on the wheel:
Engine
Brake
Headlight
Full beam
Wipers
Uncouple trailer
shifter toggles 1 + 2 if you shift
(I also have horn, L&R signals, world map and radio on the wheel buttons/paddles, but these seem optional and personal prefrence)

I use a Thrustmaster TMX wheel and pedal set and I have mine setup as such:
The paddle shifters act as my left and right turn signals. (I'm running automatic trans until such time as I can add a proper shifter).
The A & B and RB buttons control my lights, wipers and horn. (lights on/off, HB, wipers hi/lo).
The Y X and LB buttons control my cruise control system. (set, accelerate, coast, resume).

Stuff like beacons and other 'odds & ends' I leave assigned to the keyboard.

I use joy2key so I can have "tap" and "hold" commands for each button on my G25.

I'm on with G27 and shifter. Left and right pedals on wheel for turn signals. 6 buttons at the wheel for lighting, bright light, alarm set on the left. On the right top to bottom, horn, gps change and last the handbrake. Top 4 buttons on shifter I use for radio to change turn on/of and volume. D-pad usage for motor-brake wipers, diverential brake and i forgot the other one I think it's lowering for trailer. 4 lower buttons for ignition, starting, release trailer and zoom map. Thats it. Oh the wheel itself, I use for .....U guessed it!

G29 here.
X = Hazards
O = Parking Brake
Square = Ignition
Triangle = Headlights
Red dial left = Retarder down/Engine brake strength down
Red dial right = Above but increase
R2 is... nothing? I guess
R3 is Headlight flash
L2 is shift toggle 1
L3 is shift toggle 2
Share is Quicksave
Option is Quickload
PS is Horn
Red dial button is activate
+ is Cruise up
- is Cruise down
DPad Up = Wipers
DPad Down = Trailer attach/detech
DPad Left = Cruise resume
DPad Right = Cruise set
Left Padal = Left Signal
Right Padal = Right Signal
And I have a USB encoder that I use to have a held jake brake

I use this exact layout on almost every driving game I play and it works out just fine.

Forgot to mention that I use Eaton Fuller 18speed.

My g27 steering wheel crashed on me so i pullout my old Genius and coupled it with the g27 shifter and foot control. dont have the 360 wheel but i am stiil able to do some hauling.

The G29: I use the paddles to operate the shifter ranges (I have the TH8A shifter). Thumb buttons for turn signals... I am forever trying to use the phantom signal arm that doesn't exist on the game sheel that does come from car steering wheel, and then when I drive my car I use the thumb buttons on the wheel to signal when all that does is mess up the car radio.

Misc buttons for hazards, headlights, etc. A button to do trailers. The center buttons for parking brake, map, and pause. The dial button for the jake brake toggle and the wheel to tune the radio. Up and down buttons for radio volume.

I've maxed out all the buttons on my G27, if I ever get my simulator setup properly (even though I'd need a keyboard tray because I play a lot more than just driving games) I'd need a button box or the side-control from the Logitech/Saitech farm-sim wheel.

On my wheel
LH top to bottom:
Cruise activate
Cruise up 5
Cruise down 5

RH top to bottom:
Camera zoom
Engine brake up
Engine brake down

Shift paddles are my indicators

On the shifter I use the full manual H-pattern (E-F 18-speed in ATS, Volvo 12+2 in ETS2)
Shifter red buttons L-R:
Range Select
Engine Start
Enter (accept jobs, refill fuel, sleep, buy garage etc)
Gear Split

L: Lights (Off - parkers - low)
R: Wipers
Up: High beam
Down: Hazards

Diamond above D-pad:
