As I understand the "gate numbers" on relays, the first image I posted won't work. It is getting signal to an output gate. The input gate is number 30, 87 and 87a are outputs.

I guess the concern would be potentially causing the OE reverse lights to illuminate when operating the lights via the switch as it would have 2 positive feeds...

 

sorry I don't have a circuit drawing degree or fancy software....

this might work...



but to be absolutely sure there's this way also....



BTW...these were done at 80mph....

i was bored driving home on the open prairie

 

I have my aux reverse lights wired to a SPDT (on-off-on), which allows the lights to be either on w/ reverse, always off, or on w/ parking lights. Very simple to wire w/ a 4 pin relay, and I think it does what you are looking for. Link to wiring ... https://www.f150online.com/forums/el...uestion-2.html

I've also wired my grill lights in a similar way ... on w/parking lights, always off, or on w/ high beams. Makes it convenient to use them as driving lights on roads w/ light traffic.

 

Hmm, the rusty brain is trying to remember series and parallel wiring... Gad I hate forgetting important stuff!

My brush guard lights are wired with a pre made KC HiLites harness, No tie in to existing circuits...

 

I'm completely clueless when it comes to wiring, but I'm pretty good at copying people on the internet.

 

series would be power light light ground

parallel is power light ground
sharing power ground for second or more loads

 

If you are following this, and want to follow the project, I have the first post on it including links to the materials posted on my blogger blog at http://daves-workshop.blogspot.com/2...nd-7-pole.html.

 

Or how's this:

Series + ---o----o---- ll
Parallel + ==8===ll

Series shares source voltage, so two lights on 12v each gets 6v
Parallel each load gets full source voltage

 

Okay what about...

| /----Switch----\
12V power --- - ---- Lights
| \-Reverse Wire--/

 

Second installation of the LED reverse lighting blog series is up...

 

I have the video of the Tee splice in the reverse light wire from the 7 pin wiring harness posted on my blog. Take a look. not the best video work but it gets the point across, I hope....

For those following. I have updated the blog post with fresh information, and a mess of photos, including an updated wiring diagram for the relay circuit...

 

I got the fuse holder soldered to the main lead last night, and ring connector installed. I shot some video of it, however I am not happy with having the demo version crap on my video, and the audio needs work. I have the full paid version of PowerDirector, and a Behringer Podcaststudio USB rig coming in shortly, I will edit the footage and lay down a sound track for that so it should be more professional in appearance, and sound, as well as being easier to follow. The weather is turning foul on me today, so chances are the under vehicle stuff is NOT going to happen tonight. Oh well...

 

that sux....

 

Could be much worse. There's a hurricane out in the Atlantic (bad), it's not aiming at me (good)... All in all, I can piddle around a couple of days, build the underhood and under dash portions of the harness so they are ready then do the under truck run and final install all in one fell swoop. Won't be this Saturday as I have business obligations at a custom car show, but Sunday should be free...
