I just installed the DEI Valet 712T on my '97 and it worked great first time - door unlock/lock, horn honk, parking light flash and domelight supervision. This system also has the capability for progressive unlocking but I wasn't sure how to wire it. The car itself has this as a standard feature when using the key in the drivers door - turn once to unlock that door only, turn twice to unlock all doors. So I'm thinking I don't need to add any relays to make this feature work, I just need to tap into the right wires from the drivers door. Any ideas?
