the cmoputer was wacky. The Saab Lock relay will do all the work you want. It was designed to handle the load of 4 lock motors. You will need to rewire the actuator (2 wire) from a switch (3 wire). What I do is remove the 3 pin connector housing from the switch and put it on the pigtail from the motor which you will put in the driver's door. Now you need to make a couple of adapters to go between the lock relay connector and the lock relay (above RHS heater duct). I make 2 straight pieces of wire with a male spade on ione end an a female on the other. These bridge the power and ground from the collector to the relay. I make 2 'Y' pieces with a female spade and 2 males. The female goes on the relay at the 'lock and unlock" pins. One side of each 'Y' gets connecgted straight pin to pin the other branch connects to the appropriate wire which used to go to the door (position 1 and 2 IIRC). At this point, you can test it to see if all lock and then unlock. Ground each pin required to actuate the lock relay (1 and 2 IIRC, but check the Bentley). Now if it all works, you are ready to hook it to the keyless entry module. Most of these can deal with the different types of lock actuation for many types of cars, What you are looking for is a short ground signal on 2 different wires to lock and unlock. Connect these up to the appropriate pins of the lock relay and you are done. I also add a DPDT relay to flash the turn signal lights (I tap into these at the back of the hazard switch (wh/r and wh/bl IIRC). Others suggest using the marker lights (pin 57 at the headlight switch IIRC), but this flashes the dash lights as well and will pop a 5 amp fuse with the initial current rush. Besides, the later cars (NG900 and 9K) flash these and it looks cool.
