If you use multiple inputs while sending a tx then it'll be linked of course.
let's say wallet A has 5 different addresses and
add1 has 0.1 btc
add2 has 0.3 btc
add3 has 0.1 btc
and if you want to send 0.5 btc to wallet B's address
if you don't use coin control and choose inputs seperately they'll be in same input, so those 3 addresses will be linked.

But is there a script online that takes a couple addresses as input and tells you if they're linked after analyzing the blockchain?

What about using a mixer? I've thought about using one like Bitmixer, but would that cut the trace of your original coins?
And what if the origin of the mixed coins you got are criminal coins? (coins that are linked to for example Silk Road or something).
I dont know if you get my point, let me know please. Im willing to learn how to do this, but I dont want to get in trouble, I just want privacy.

Yes. Good mixers will help you to gain more privacy. The chances for that to happen is very low. You can also use a reputable site where you can depoit Bitcoin and then withdraw it after some hours or next day. If you are doing this, you must ensure that:

 • deposit address isn't used for sending coins withdrawn.
 • deposit address isn't public enought to know the name of exchange.

Do you know of a website or etc that can determine if addresses come from the same wallet?

I'd be interested to know if something like that exists yet too.

It can't be done unless the wallet you put a backdoor. The wallet will be marked negatively pretty faster by others if they do something suspicius. So the chances are very low.

Edit:

You can use Blockchain.info's "Taint analysis" tool.

you should be fine as long as you don't send btc from wallet #2 to wallet #1 too frequently. though if you want to be sure that you won't tracked, you can always use an exchange or a dice site to completely hide your track.

and multiple wallets "privacy" is not very different than multiple address.

Does a dice site deposit... Then withdraw, act as a true mixer? I would think the taint would be rather high... Perhaps even some of the withdraw coming back from the original deposit address

Just curious.

I think the best way, in my view, to truly mix coins would be to deposit BTC to an exchange, say Bittrex... Buy Doge or another coin thats high volume low volitility.  Withdraw Doge. Deposit Doge to different exchange... Say poloniex... Sell for BTC. Withdraw.

I'm sure you mean address not wallet

So, in this case ask sender send to address #3
The sender won't know about address #1 & #2

The wallet/address distinction is important here.  If the 3 addresses referenced above are in the same wallet, there exists the possibility that they will be linked when spending coins in the wallet.

The users have to choose input manually, so these addresses won't linked together
Most wallets like blockchain.info or electrum already support this feature

That's what "coin control" is.

Both Blockchain.info and Electrum only supports us to choose two options when sending: "any" or "an address". So you can't choose inputs as you like, only address to send from.
