hi, on the weekend im looking at installing my headunit http://www.ebay.com.au/itm/Alpine-iDA-X ... 2460wt_955

in my old xe fairmont ghia, was wondering if i will have any issues with this? will it have the same wiring setup as my ef? will i just be able to slam the cables together and bingo? really hoping not to have to run any new wires throughout the car any help appreciated thanks
