561r parking light hookup

You will have to try it.  I think it is going to be longer than you are thinking. Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB

.4 seconds will be a long, loud honk. If you have a stopwatch handy (my cell phone has one), try it by hand and see what you think. Most DEI systems with a horn honk output have a 50-millisecond (0.05 seconds, right? I think) output. It's obnoxious and too loud when it's late at night. The Audiovox systems I install have a 16-millisecond as a default....sounds just about (but not exactly) like the factory GM horn honk. I, too, don't care for the 561R's single lock/unlock button. I'm sure you've realized this by now, but for just a few dollars more, the 562T would have given you a second remote, proper lock and unlock buttons, and a horn output. Doorlock switch: They did make some Silverados with power doorlocks, but without power windows. They might be a little rare to find at junkyards. You might try to see if you could get those switches from either the junkyard or a dealer. Otherwise, you could just find any switch that suits your taste.........you want this: SPDT, momentary, center off ........... that is, Single Pole, Double Throw.........momentary (only stays in the "on" position while your'e holding it) center off (like it says, at rest you're in the "off" position). You could get some kind of toggle or rocker switch from Radio Shack or partsexpress.com. You might just look around the junkyard for any kind of car that has a power doorlock switch you think would look nice in your truck. At any rate, so you have that 451M in there, right? And you remember the small, three-wire cable, that goes from the 451M to the 561R, right? Just splice into the small green and blue wires in that cable....... applying a momentary ground to the green will lock the doors, and ground to the blue will unlock.

So you are not going to try the Relay, capacitor and resistor?Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB
