I have it currently set up for single axis which work's fine in mame but recently installed OR coast2coast which is looking for dual axis, does anyone know if it is possible to wire this on the great A-pac???
Regards.

Yes.
But how depends on your current setup, which model of apac, and what changes you want to do. :D
I'll assume that you only have a wheel attached to one of apac's analog ports, and the two pedals in series attached to another analog port. Again, assuming that's all you have hooked into the apac, with apac ver. 1, that leaves 2 analog ports open, and with ver. 2 leaves 4 open.
I can see two things you might want to do: convert completely to separate dual pedals, or be able to switch between split & combined pedals. Both are possible if my above assumptions are correct. Mame is able to work with either combined or separate pedals as long as the game with dual pedals is emulated with separated pedals (vs both on the ad_stick Y axis), or the game has only one pedal. OTOH, some PC games only work with combined pedals, some can do either, and some want separate. So it's up to you which way you want to go.
The easyist is to to convert to separate pedals. The second can be done with a 3-way 3-pole switch (I think) ;D. The details differ on which version apac you have, so could you tell us which version you have before I go into details?
FWIW, most comercial PC wheel/pedal sets that have separate pedals can combine them into one in the driver / firmware, instead of a hardware switch as I'm suggesting.

It's a version 1 A-pac, I am assuming c2c want's dual axis because if you set the accel pedal then set the brake it makes the accel pedal unnasigned. Currently I have the steering wheel in the left/right axis & the accel pedal in the up, brake in the down all on player one side. Might have known the expert on analog would answer this first!!!
Also had a look at my bible(st.clair book) this explains how to do it via the parallel port but I am sure at time of print of the first edition ultimarc hardware was relatively new.
Thanks u_rebelscum.

Heh, searched google, and found this thread (http://forum.arcadecontrols.com/index.php/topic,36092.html)that includes switching pedals with an apac ver 1.

Ahem :-[ after my initial excitement at the way andy describes it im not sure I understand it, diagram anyone?
Wire the pots as normal to the P1 side of the board.
Then connect the following wire links:
1 Right to 2 Up
1 Down to 2 Down
1D to 2D
