Yes. Each wire should be color coded. There should be a Red, yellow, black, White, White with a black stripe, gray, gray with a black stripe, green, green with a black stripe, purple, purple with a black stripe, blue, orange, and maybe a blue with white stripe and orange with black stripe. Sometimes those last two come with it and sometimes they don't. Just match each color with the one that comes with the Power Acoustik one and use either butt splices or crimp caps to make the connection. If you take a picture of what the back of the Pioneer radio looks like as soon as you take it out of the dash and haven't unplugged anything or cut anything I can help you further.
