smoke, fire, what happened?

Are you saying that you cut the pink / YELLOW and pink/lt. green and connected the wires from your relays to the side facing the driver's door? Or that you connected the wires from the relays directly to the pink / YELLOW and pink/lt. green without cutting them? The first case would probably cause a short circuit, since most older reversing polarity doorlock systems are grounded through the driver's side switch. The second case definitely would be a short circuit. It's really not worthwhile to worry about avoiding the passenger actuator(they are dirt cheap to replace, and it'll be a nuisance the first time you want to get in from that side).C Renner's Auto Electronix

In the door harness, there is a lovely fused power source for the door locks already. It is BLACK/ white. 87 on both relays to 12V, 85 as well. 87A goes to switch side 30 to actuator side. 86 is negative trigger from starter unit Sounds like you have switch and actuator backwards. This sounds hack, but this is the easiest way to find switch and motor side. It works 100% of the time, and you definately know which is which. Cut one of the lock or unlock wires (in your case, cut, say the pink/green). Take a fuseholder, put a 15A fuse in it. Put one end of it to the +12V for the locks (why? because it is right there with the other two wires..... no sense over complicating things). Now, you have 2 sides of the cur wire, right? Touch the other side of your fused 12V to one of the ends of the cut. Big spark, fuse blows, you just found your switch, as it rests at ground. Doors lock? You just found your actuator side. 87a on one of the relays goes to the switch, 30 on the same relay goes to the actuator side of the cut. Repeat for the other wire (or, now that you figured out one of them, the other wire is wired exactly the same, using the other relay). 5 wire locks aren't that bad at all...... too many techs overthink them, and in the end cause far more work than necessary for themselves.Wherever I go, that is where I end up......
