How to Replace the Steering Wheel in an Aston Martin
This is a fairly easy job to do and only takes a couple of tools. I replaced the standard steering wheel in my grey V8 Vantage with an Alcantara one from Aston Martin. It's the same process regardless of whether you use that steering wheel or another.

T30 Torx bit
T50 Torx bit
Ratchet and short extension for the above Torx bits
Small flat-head screwdriver (recommended)
Painters tape (recommended)
About half an hour
Insert the car key. If you have the older Volvo-based key, turn it to position 1. If you have the newer crystal key, push it into position 2. This will release the electronic steering column lock and allow you to rotate the steering wheel.
Disconnect the car battery. Wait a couple minutes to allow any residual charge to clear. This will help prevent the airbag from accidentally deploying while doing this job.
Turn the steering wheel until you can access the T30 Torx bolt on the backside of the steering wheel. Remove that bolt.
Turn the steering wheel back the other way until you can access the second T30 Torx bolt on the backside of the steering wheel. Remove that bolt.
Carefully put the airbag module away from the steering wheel to release it from the snap fittings holding it in place. Do not pull it completely away from the steering wheel! It is still connected by some wires. Turn the airbag module over as much as you safely can so you can see the wiring on the back. Flip the yellow safety tab up on one of the connectors and then press in on the sides of the connector to release it from the airbag module. Pull the connector away from the airbag module - straight back from its rear side, do not try to slide the connector along the surface of the airbag module. Repeat for the second connector, then set the airbag module aside.
Loosen (but do not remove) the T50 Torx bolt in the center of the steering wheel. Once there is some space between the steering wheel and steering column, slide a thin flat-head screwdriver between them to release the steering wheel wiring harness. Once the wiring harness is disconnected, remove the T50 Torx bolt and steering wheel.
Use a piece of painters tape to keep the plastic rotary coupling aligned (use the red tab and corresponding notch for alignment). Guide the airbag wires through the hole on the steering wheel, then carefully press the steering wheel in place and start threading in the T50 Torx bolt. Before tightening that bolt, remove the painters tape. Torque the T50 Torx bolt to 40 Nm (29.5 lb/ft). Connect the steering wheel wiring harness.
Reconnect the two connectors to the airbag module. Make sure the wiring is safely positioned while you set the airbag module back in place, then press it in to snap the three snap-fittings back in place.
Turn the steering wheel to give you access to hole for the T30 Torx bolt. Insert it and torque it to 9 Nm (6.6 lb/ft). Turn the steering wheel to the other side and repeat for the second T30 Torx bolt.
Reconnect the battery.
