I am adding a few electronic devices to the Suburban and I am at the point I need another fuse block so I am not cobbling up the factory one with additions. Right now my add ons are a usb port, rear view mirrior with compass/temp, 700r4 lockup, and a glow plug over ride with 12v relay. I see stuff coming up in the future and I'd like to know what you guys are running.
