help! I screwed something up! I bought the exact same unit you show in the pictures. No problem getting power and having the module click on and off. Once I tried to get the lock and unlock hooked up (I have a W124 under the seat with one green, one blue, and two yellow wires) the module stopped functioning all together (pump and locks still work fine). Before I tried lock and unlock wires, it was clicking on and off with the blue light flashing then on one attempt it just stopped working. Should I have spliced all three top wires together or just one (which is what I did) and bottoms? Can the unit be reset? There is a button on it but no directions on how. Fuse did not blow so I'm thinking I shorted something out internally
