Electronic devices are becoming more common in race cars today and these devices typically require lots of wiring to connect everything. This is especially true with cars using multiple stages of nitrous. Each stage requires wiring to a nitrous solenoid, a fuel solenoid, a wide-open throttle switch, common power feeds and fuses. Usually, relays are added to handle the high amperage draws. Dedenbear has designed a relay center that prewires all the relays in a single unit. Basically each stage has a signal wire going in and a power wire going out. The inputs and outputs have indicator LEDs for easy trouble shooting. All of the wiring mess is replaced with one simple, compact and reliable relay center.
