Help? Replacing OEM stereo to aftermarket Pioneer HU

[darkcolor.666]

Hi all, so i took out the old OEM tape deck wanting to replace it with a Pioneer i purchased from Bestbuy. But i am unsure how to do the wiring. Can someone please help me? Do i need some sort of adapter?

This is the rear of the new deck

Wiring a deck is not that difficult at all, it is about about color matching....but things can be complicated if some one else has done poor job before you.

1 - Did all functions of OEM deck worked properly? fader, balance, power on/off...if they everything was well, then it would be safely to assume it was wired in properly, it could be messy, but at least properly. This will rest assure you're will not be dealling with messed up wiring.

2 - Use the OEM color coding to match the wiring from the car to wires comming from the deck. I beleive the sticky will have the color codes for the wires. In theory, you're dealing with a dozen or so wires, where 8 of them are for speakers, the rest are ground, power source and constant power. Use the installation manual from your deck to help to understand what each wire is for.

Read the Sticky, print it. use it for the install. Thank Luke later.

Current wiring after pulling out old OEM tape deck

OK, see how there are 3 bundles? First, there is the bunch attached to the fader. Unplug the fader, you will need the wiring there.

Second, the bunch that connects to the fader wiring and runs deeper in the dash is you deck harness. You have it VERY easy, you can is one of the easiest E30s there is.

Use the color guide in the stickied thread, should make it easy for you.

Oh yeah, that third bundle, the one on the left..well, that ain't radio stuff, you ripped wires and lights out of the heater controls.

Lemme know if you get stuck, this one is super easy.

Thanks guys. I was looking at the sticky yesterday and I m starting to understand it. I m confused from the sticky about the 'speaker wires'? The portion that's on the car right of the diagram, which suppose to be wirings in the trunk? I m going to worry about that later.

As for the new head unit, it comes with a metal frame thing that for securing the headunit to stay in place. Do I install the metal frame to the center console first, then push the head unit in, or do I leave the metal frame on the head unit and push the whole thing into the center console?

Sorry guys this is my first time, be gentle. :)

i've used this guide several times and it's perfect. when you access the amp in the trunk, you just have to connect the Dash Wires to the Speaker Wires in the trunk. this is because you'll be bypassing the oem amp but you'll reuse the wire harness which goes to the specific speakers already wired in the car. :)



Obviously, what you do here is simple: connect the "deck" wire to the "dash" wire, then back at the trunk, connect that "dash" wire to the "speaker" wire.

This is not rocket surgery, boys. Get it done.

I m not installing any amps, I m just replacing the head unit, why do I need to do anything in the trunk?

It's because if you don't rewire your trunk, you'll use the Oem amp in trunk. The diagram bypasses the stock amp but allows you to reuse the wires and connect inputs under dash. Other option is rewire from scratch. You don't want I do that.. Do you?

[daytonaviolet]

sorry for the confusion. basically that link explains how to hook up an after market head unit and still utilizing the stock speaker harness. the stock setup from bmw goes like this head unit --> oem amp --> speakers.

this instructions explains how to hook up an aftermarket head unit (use the power from the head unit) and also bypass the stock bmw amp.

if this is not what your after, then ignore that link above.

I m confused...

What about my question about the metal frame?

[Skunkworks]

Yes you will use the metal frame, get every thing wired up make sure that it works including your heater control wires that got pulled out and all the bulbs are in and working.

Test fit the frame once it fits right push the tabs in to the dash plastic and slide the chassis in. Make sure to get the wires so they are fitting nicely in the hole, click it in and install the metal trim.
