Hi Guys, Yesterday i bought a 'pzq60-0021' CD player out of an '07 Hilux and i have fit it into my 2003 camry. I was just wondering, there are 2 unused plugs in the back of the unit. Circled in blue is what my old head unit had, and what i have plugged in, circled in red are the empty ports. What are these for? i would assume maybe steering controls/sub woofer or the like? Any info would be appreciated :) Thanks!
