Updating a standard Omega steering wheel to HSV
Assuming the boards are the same shape you could swap them over...
Thanks for the tip. Yes - they are the same shape. It took some careful dis-assembly and reassembly but it wasn't actually all that hard. It's one of those jobs you just have to poke along slowly and don't break things!
Since the lights are soldered onto the board exactly as you suggested, i just carefully removed the old loom and disassembled them and put the nice new button (and Volume wheel etc) covers from the new HSV media button set ($77 Holden) onto the old Omega boards and clipped them back together. Then i just inserted the HSV media button fascia's into the spokes that came with the wheel - and "Hey presto" - done!
For anyone wanting to do same: There is about three parts to each side, and they're held together with 4 little plastic locator lugs that come apart easily with a small blade screwdriver, and just be sure to work a bit on all four tabs together so it comes out evenly and doesn't break.
So i now have an HSV wheel, with HSV media button covers and fascia etc, with the original Omega wiring loom behind it, so the illumination matches the rest of the green theme!
Thanks for all your help.
