I have an Ungo ms8300 in my 92 mustang, and I finally have gotten around to wiring up the power locks function.  When I arm the system, my doors lock, but when I disarm the system, the 15A fuse to the 12v wire of the relays blows:x .  3 tries later and I'm all out of 15A fuses and Radio Shack is now closed.  Should I use a larger fuse?  When I ordered the inline fuse I accidentally got a pretty thick gauge wire - probably around 8-10 ga -- could this be a problem?  I've connected the 12v relay wire to the 12v ignition wire and I'm also using the lock/unlock wires directly from the passenger-side switch.  Any help/suggestions would be greatly appreciated.

You should try and switch the motor and switch legs
to the unlock side of the relay. When these legs get wired backwards they will blow the fuse. This should help you out..........
