I've never been a fan of cutting into factory wiring to power stuff and while the s2000 has a few spare fuse terminals under the dash that only scales to one or two devices. I need to provide power for two SPA digital combo gauges, a boost controller, and the V1 radar detector so tapping into wires and using the extra fuse terminal won't work. To provide enough circuits for this stuff I installed a small six circuit fuse block from .

The extra fuse terminals are themselves fused by a 40 amp fuse under the hood (fuse 42) and each of these devices should draw no more than 1-3 amps each so I feel pretty good about it. I'm going to clean up the wiring with better sheathing and heat shrinking when I install the gauges and boost controller, this was mostly a mock-up to get the V1 hard-wired . The fuse block being slightly tilted makes my eye twitch and it needs to come over about an inch to the left.I also added a microphone for the stereo's bluetooth feature. It's just to the top left of the dome lights and is pretty stealthy. I don't think you can really see it unless you're looking for it. Head unit is a Kenwood KDC-BT885U with Modifry wiring harness and DCI. Stereo door is currently rough looking because I had to get it back together but will be cleaning that up this weekend.

 

Neat job! Doing electric wiring correctly will play off, in much less future headaches. I draw up wiring diagrams or schematics after each mod. Makes future mods & fixes so much easier.

 

 

I did the same thing. Cheap amazon block with 8 acc. Powered off the single source from the fuse panel as OP did. Seems to work great, no problem. Ive got 6 acc plugged into it.
