I have an RV with a power awning. There is a momentary switch inside on the wall for extend, retract. I decided to add a second switch for this in the outside storage area so I could put the awning up from outside as well. On the back of the existing switch, there are 4 pins and 4 wires. Orange is the hot wire, White is the ground, Red is the "extend" and Black is the "retract". The only dpdt switch I could find for the addition had 6 pins on it. I found a wiring diagram on here for wiring a dpdt switch for reversing motor polarity (which I assume is what they are doing here) and wired the new switch accordingly. I tried the new switch while the existing one was disconnected and it worked fine. I then reconnected the existing switch and tested it and it also worked. However, when I try the newly added switch WITH the existing one connected it pops the fuse. I don't know where the issue could be?
