Directed Install Essentials 451m Door-lock Relay Assembly

[Music] today's video I'm going to talk about making sense of these internal door lock relay wiring scenarios that they have in all these directed electronics alarm and remote start combo systems I get a lot of people who ask about these things all the time and here's why because in a typical alarm system or a remote start whichever they always have transistorized negative outputs which typically trigger an external relay something like this even people that are used to looking at relays and wiring relays like this are actually thrown off by actually how this wiring in this harness just doesn't make any sense to them at all and I can understand exactly why it began way back when when they used to have the 451 external relay pack which did five wire and actuators negative positive one wires and people will get the books and just look at them and go hmm no one can understand what the heck
