IS300 Fans - How to wire them

I used two "add-a-fuse" circuit taps for my two 10 amp relay fuses, but how would you suggest that I tap my three 30 amp fuses into an ACC power source? Can I unscrew the power wire that leads into an ACC fuse in the box under the hood and tap my 30's in that way or will that over load the circuit?
Thank you for all your help

FWIW, I love my IS300 fan setup. I actually bought a new 'OE-Aftermarket' version of the fans that I've been running all year (made by Sunbelt). I personally just wanted something new rather than a used set of actual OEM Toyota ones, so I gave em a shot.
There was some question as to whether they would work as good as the actual Toyota ones as the fan blade design is different. But I can attest that they do in fact work excellent. Mine is setup to just use the stock temp sensor and is controlled by my standalone. We have em setup to kick on at 190 and shut off at 180. No low speed control, just both On Hi-Speed or both Off. We don't see AZ temps here in MN, but we've had days near 100* where I have the A/C running on full blast, and it all still runs like a watch. My temps never even reach 200 under normal driving even on the hottest days we get up here. Highly recommend this setup to anyone interested in switching over to E-Fans. The built in coolant overflow is really nice as well.
I did adapt these to fit on my OE Denso SC300 radiator. The simple brackets I made, I've uploaded the design to the 'CAD File Sharing' thread on here for anyone else who wants to use them. It's a very basic/crude means of adaption but it works and costs hardly anything, and all the measurements are right there for you in that thread making it super simple to make your own. One of my local friends here is working on a much nicer and more elegant adaption setup that I can't wait for him to finish. It'll cost more but is really nice.

Bumping this amazing thread back up… loads of helpful information to read but I have a few questions for Gerrb. I read all the post on different ways to hook up the fans, since I’m still on OEM ECU I’m leaning towards using the coolant temp sensors to run the fans. Only thing is I purchased a PHR dual fan PnP kit, and I’m about to order OEM replacement IS300 dual fans, is there anyway to incorporate the PHR kit into the coolant temp sensor setup? That way I actually use the kit and don’t just let it sit there and be a waste of money. Thank you for any help in advance.
