Description
My thoughts exactly

#8 Wallyb4 Retired EWC(SW/AW) 1983-2003 I did and nothing was labeled That
Also, keep in mind that these taps can only be plugged-in in one direction

#20 What I want to hook up needs to be on the accessory side, not constant power

I've edited my post above to make this clearer

When you insert a small 20 fuse, the outlet will alternate power with the truck on/off
