dodge ram 1500 1996 locks/door

the previous owner had an alarm with remote start already. the door locks did not work when i purchased the car. i discovered when installing the system that at splice was put in and i undid that damage. the locks still dont work normally. how do i tell if the relays are still in there if i cant find them visually? the 10 pin connector was unpluged and the unlock/lock signals were cut and the red wire was spliced. there is no V on the red wire(maybe there is suposed to be). 2nd on my alarm there is an input for the door wire + and -(two seperate) should i only be using the one that coresopnds to the wire i found or do i need to find 2 wires for the door plug?

ok i solved these 2 problems. (blown fuse for lock, bad connection for door) in general what does the brake notification wire do?

If the vehicle is broken into while remote started, the vehicle will shut down if the brake pedal is pushed.
