@Dinsky For dashcams a 2A fuse size is ideal but you are safe with a 5A fuse too. The fuse type you need should be listed in your Owner's Manual or given on the fusebox diagram sticker. Just a few details to watch for doing the install-
-First be sure of the ground connection; many visible bolts and screws may not actually connect to the chassis or may not connect to it well.
-Second be sure to ifentify the wires propperly; there will be tags on them or their function will be listed in the hardwiring instructions with the HWK kit.
Wire colors and their function can vary between kits and manufacturers so do not presume based on wire color- always check the tags or instructions.
-Third is to never tap into a fuse which is smaller than the added fuse for the cam, and best to tap into one at least somewhat bigger.
-Fourth is to never run cabling in front of any airbags; you can usually find some factory wiring around where you need to go so just follow it's route exactly.
Which fuses to tap can be a problem as many vehicles now use delayed circuits or computer-controlled power shcemes. You will need a DMM (voltmeter) or LED test light to check these.
Never tap into a safety-related circuit such as ABS, PRS (airbags), ECM or PCM, brake lights, taillights etc. For the ACC wire a few suggested places are power windows, radio, heated seats etc which operate only when the key is switched on. Finding the fuse for a BAT connection may be trickier, but usually the keyless entry fuse will have continuous power.
Delayed or computer-controlled circuits can seem good for this but drop power later, so if you have problems this is usually where they're found.
It's not hard to do, just take it step-by-step. If you aren't comfortable with this level of DIY any car audio shop can do this for a reasonable cost. Your toughest issue will likely be removing trim parts to run the cabling. If you don't have the little plastic prybars to do this (sometimes supplied with cam or HWK) they can be bought for a few bucks at any auto parts store. Just go gently and carefully and don't use excessive force such as seeing the trim bending very noticeably at your pry tool but still not releasing. And if you have any problems just come back here and someone will be her to assist. That cam is one of the better ones IMHO so I'm sure you'll be pleased with it.
