No Fuse on Aftermarket Wiring Harness???

[jrut224]

I have an Alpine CDA-9831 head-unit, and unfortunately lost the original wiring harness when I removed it from my last vehicle. I purchased a new harness (http://www.sonicelectronix.com/item_4265_Alpine+16+PIN+Head+Unit+Replacement+Wiring+Harness.html ), but it did not have the fuse setup on the battery-power wire like the original did.

I assume I need this? I don't understand why it wouldn't be included with the aftermarket...

Alpine describes it as a "choke coil w/ fuse holder (10A )" ... would a 10A inline fuse work if I picked one up from the hardware store, or does the choke coil do something more than just protect against a jolt?

Any suggestions???

Thanks in Advance

Or rather, is this essentially what I need?...

I found that the choke coil cuts out noise from the vehicle power.

If this is infact what I need, would I still need a 10-amp fuse holder like I mentioned before? (I know that my original harness had a 10A fuse, but I can't tell if this noise filter has a fuse setup included, or rather if it is just for 10-amp system.
