Hi I recently bought a DEI Rattler 369D Remote Start and Keyless Entry Unit. I don't plan on hooking up the remote start feature yet but how do I at least hook up the Keyless Entry feature. It came with a DEI 451M relay but I haven't the slightest clue as to how to hook it up to the vacuum lock and in turn how to hook it up to the 369D unit. I'm not worried about the factory alarm because I had it disabled. Please help.
