wireless Ps2 controlling Rc Car through arduino Uno in need of assistance

i hooked up a wireless ps2 controller up to the arduino uno… the receiver is in sync with the controller
but when i upload the ps2 library i get this reading

No controller found, check wiring, see readme.txt to enable debug. visit www.billporter.info for troubleshooting tips
Unknown Controller type

note that the wireless ps2 controller receiver has 7 pins
while the regular ps2 wired controller has 9 pins

& im not sure how to determine witch pin is witch… i know witch pin the ground an power are,
an as far as the other pins i just followed the regular ps2 controller wire schematic
