Keyless Locks Shorting Out

Well, I got a pair of new actuators and a keyless entry system and put them  in my vehicle that already had power locks but bad actuators.  When I ran the wire from the reciever to the locks, I attached it to the factory wiring that I attached to the new actuators.  I don't know what is wrong, maybe the whole thing, but when I try to program one of the remotes to the right frequency or use the one that is already programed correctly, it blows the fuse on my power input wire.  I tested it with a multimeter and the ground wire reads at 2 Ohms.  I know that means the current isn't running through the system correctly, but I don't know what to check for. 

Please offer any suggestions if you are familiar with this sort of thing

I got new actuators and removed the oem actuators.  The car had factory power locks on it already and I put my aftermarket actuators on the factory wiring.  I ran the wires from the Keyless entry reciever through the boot in both doors. 

My car is a 1991 Pontiac Sunbird if that helps.

So, If i just disconnect the factory wiring it should work?

If that works, will I be able to use the lock/unlock switches already in my car?

If so, how?

 those actuators need 2 relays two operate they will not work without them. what usually triggers them is a negative pulse from an alarm so to make the switch work you will have to make it send out a negative as well to triger the relays.This may require an additional relay for the switch. what kind of car is this in ?

it's a 1991 Sunbird, and I don't have an alarm, I just got the reciever and the lock actuators.

The reciever has the relays built in that I need for it to operate, so do i need other relays to make my factory switches and wiring activate the actuators?
