Upgrading stock head unit to 2014 lancer head unit 09 ralli
 

So I picked up an 09 ralliart.the seller gave me a 2014 mitsu touchscreen head unit. P/n dy-5mu4r69.He told me he tried putting it on to replace the stock one but it didn't work.he said I would have to splice some wires to make it work. My question is "what wires do I have to splice to make the head unit work?any other bits I need like wire harness or what to expect

check this sygav ralliart head unit, plug and play, it doesn't have to splice any wires, https://amzn.to/2rA9CZT
