97 explorer door locks

can anyone figure out why i can't get my door locks to work , i tried everything, even purchased one of those polarity switchers, test with dmm. every time i connect my lock wire from the alarm to the lock wire on the car it starts locking the doors, the negative doesn't do this and works fine, also the dome light output doesn't work. it has a 500ma - output that i connected to a relay and it didn't work what am i over looking

lets start off with the model of alarm/remote start unit.....Good Luck

Ford dome lights are usually (+).  I am too lazy to go look at the tech sheet for your car right now to be certain though.

it's the scktek galaxy 5100rs with the 2-way color remote
