Even with the use of a 5 pin relay, for example? That's literally all I'd want at the moment - I didn't expect this to get carried away into photometric sensors that leave lights on for 10 seconds after the car is turned off etc etc. Like I said, I massively appreciate it and it sounds amazing (and be sure to show us when you're done), but I'm just interested in turning the parking lights on when the courtesy lights come on.
So is there a way to do this with a simple bit of wiring and relays? This is me talking off the top of my head and probably absolute rubbish, but could the courtesy light's ground wire be wired into a relay, that when given a current, tells the relay to send power to one of its pins, which is the 12v feed for the sidelights? That may not make sense, but it's something like that which I'm thinking of.
Is that not possible?

the short answer to your question is yes.

ParticleWave, Meir, what do you think? Using a relay in the configuration posted in the link above?
Again, just trying to get the parking lights turn on when the courtesy lights do. No sensors or timers  that's all I'm after. |
First I need to correct PW. As I mentioned in one of my previous posts, the courtesy light trigger is positive.
With that said, it doesn’t really matter.
Once you use a relay (and you must in this case) the polarity of the trigger is irrelevant.
You just need to connect the other side of the solenoid to the opposite polarity.
The solenoids is like a bulb, it will work once it gets positive and ground in the two poles, and it doesn’t matter which pole gets which polarity. (I hope I’m not confusing too much)
If you guys a really interested to understand how a relay works, let me know and I’ll make a short video.
Back to the car.
In our case, we will need to use two relays due to the fact that the lights system is divided to left and right. You have two wires coming out of the switch, and two fuses on the fuse box. So each line needs a relay.
I was working a bit on my car this weekend, completing the installation of an “in dash” in garage opener, and started working on the electrical system of my home made PSE.
So I looked around a little bit, and it looks like the easy way to accomplish this mode, will be doing it behind the light switch. It is really simple project.
I promise to show in detailed how it’s done. I just need to find the time to do it.
