Good thing you are wondering about it.
Because it's not right.
Take a look at
my Eastern Beaver install, starting with post #4.
You really need to add a relay to this system to take full advantage of its capabilities.
Basically, the wiring will be like this:
- The red wire that used to feed the old fuse box can now be used to feed the EB fuse box.
- The red wire that left the main fuse to go to the ignition switch and come back as an orange wire should be connected to one of the two fuses near the BAT terminal.
- The orange wire that comes back from the ignition switch (the one about which you are concerned) should be used to trigger the relay.
- The output of the relay should be used to power the PWR terminal, which feeds the group of six fuses.
For convenience, you can somewhat replicate your stock fuse box with the EB box, as far as fuse placement is concerned. Starting with the one closest to the BAT terminal, think of that as your AUX fuse. (I use mine for connecting a battery tender when parked and plugging in electric vest while riding.) That can be a rather small fuse, depending on what you intend to connect to it. The next fuse can be thought of as your MAIN fuse, but it is really only going to power the relay, so it can be a 2 amp fuse with no problem at all. The first switched fuse would be IGNITION, followed by SIGNALS and LIGHTS. That leaves three more switched fuses for any other accessories you might want to install, like cell phone charger, GPS, etc.
Call me if you need to, I gave you my phone number in the e-mail you sent me.
