I wanted to shed some light on how to add a PS3 and/or PS2 to your racing cabinet. I have completely rewritten my post with updated information.
This of course requires that your cabinet uses a ps3 or PS2 compatible steering wheel. For this tutorial, I will be testing everything with my logitech driving force gt. Result may vary if you use a different wheel.
Connecting your wheel to your PC and PS3/PS2Option 1: Using a USB Switch (untested by me but, it should work as it is the same premise as option 2)

It's the cheaper route and the extension cables means you dont have to go the back of your PC or Console (For example, I have my extension cable in my Control Panel, When I want to switch, I lift my CP, unplug my wheel from one ext cable and into the other). Its not perfect but, it takes seconds and I dont have to move my cabinet to get to the back of the PC.
PS3 BackgroundAll phat ps3 and some ps3 slims (must be made before July 2010) can be jailbroken to play ps3 backups and ps2 backups. (No super slim PS3 can be jailbroken) This tutorial will not cover how to jailbreak your ps3. I had mine done by someone on Craigslist for $50. There are two ways ps2 backups can be played on the PS3 (Hardware and Software). The only PS3s that offer hardware playback are model numbers CECHAxx and CECHBxx(These are preferable and are normally sold at a premium). PS2 Software playback was offered by Sony on model number CECHCxx and CECHExx only but, thanks to advances in the Jailbreak community, all jailbreakable PS3s can now have ps2 Software playback using Custom Firmware. You can also go the full legal route and just hookup your PS3 into your cabinet but, it you will need to access it every time to change disc games and PS2 playback is only available in the first two models. The PS3 is not region locked so, you can play original Japanese racing games without having to mod your PS3.
Software playback is essentially a ps2 emulator made by Sony for the PS3. It does not have 100% compatibility, some games will not play at all and some will have graphical issue and/or playback issue. More importantly, since it is an emulator, it does
not have peripheral support for PS2, meaning
STEERING WHEELS ARE NOT SUPPORTED ON NON-BACKWARDS COMPATIBLE PS3(PS2 Software versions). I sadly had to learn this the hard way. My PS3 slim will load ps2 games but, it will not recognize my steering wheel as a steering wheel(it sees it a regular dualshock controller) which makes it useless for playing ps2 racing games.
If you want to buy a PS3 to play PS2 racing games with your steering wheel, you must purchase a model that uses hardware playback (model numbers CECHAxx or CECHBxx ONLY) PS3 CFWOnce jailbroken, you can install a custom firmware that adds features like playing PS3 backups and PS2 backups. If you are looking for simplicity, I recommend any custom firmware that includes "Cobra". CFW infused with Cobra add additional features including playing games in ISO format (makes life easier) and other options like loading games from your network or NTFS HDD.
For Non-backward Compatible PS3 I recommend "Habib's 4.55 CFW with Cobra" (Has PS2 ISO playback for NON-Backward Compatible only). For Backward Compatible PS3s, i recommend "HABIB 4.46 V1.03A COBRA EDITION" (this version has PS2 ISO playback on Backward Compatible PS3(hardware version) so, its perfect for playing ps3 and ps2 racing games).
I cannot stress enough that you should do additional research when deciding what CFW to use and that you are careful to avoid bricking your PS3 or getting your PS3 banned.PS3 Games that are steering wheel compatibleTested by me:

PS2 BackgroundAlmost all PS2 can be softmodded using Free MCBOOT (Slim version SCPH-9xxxx with date codes 8c and on cannot be softmodded). Free MCBOOT uses a memory card exploit to load external applications.
http://bootleg.sksapps.com/tutorials/fmcb/ There a multiple methods of getting free mcboot onto your memory card and there are also communities that will add it to your memory card as long as you provide the card and postage. My second memory card slot is broken, so I cannot make a copy for you. Please do not pm. Once you have Free MCBOOT, you can load PS2 backups from the DVD Drive, USB stick, ext and internal HDD and your network. Since it is not an emulator like the PS3,
peripheral like a steering wheel WILL work on a modded PS2. I have a fat PS2 and im using a spare IDE HDD to load my games. Once again, you can go the fully legal route and just add a PS2 system to your cabinet but, you will need to access it to change games and the PS2 is region locked so, Japaneses and European racing games will not play on a non-modded ps2.

The following are racing games I have tested that do NOT have steering wheel support (for my DFGT atleast, other wheels may be different)Outrun 2 C2C - Does not see my wheel and does not have wheel settings in options menu like the Japanese version does(outrun2SP).
Battle Gear 2 - (Japanese Version) / Tokyo Road Race (European version)- Although the splash screen in Tokyo Road race mentions a steering wheel, it would not see my wheel at all.
Ridge Racer V - Does not see my wheel but after a deep google search, someone once mentioned using their madkatz wheel to play so maybe its my wheel.
Road Rage 3 - (european ver) / Touge 3 (japanese version) - a budget game that actually pretty fun. its like a budget mix of initial d and battle gear. Does not see my wheel
Once I have everything in place and hidden. I will make a video. I will also add more specific information like how to load ps3 games from your PC and how to add games to an internal PS2 HDD, etc
