2020RSTBorla

Sorry for the delayed response, I was setting up and running sound for a multi-band private party that took up most of my weekend. So I ended up wiring the DPDT relay I got Friday. It is much quieter than the 2 relay solution. See the DPDT relay schematic above. The only issue I am having still is that when the door is opened and it switches to door assist lighting the dome lights flash once or twice and then come on. All other functions in all other situations work unless I forgot to test something. So to your question, where am I drawing power from? I am getting power from the Passenger side F-22 ACC/IGN and F-46 BATT via 10A power taps. The only effected part of the relay when it comes to the PIN 23 GY dome trigger wire is the relay coil. Everything else is isolated. There is no draw on the coil side. At least there shouldn't be other then what the coil needs to activate. When the dome lights fade out everything works correctly. The coil holds on until the dome lights go out and then it releases at the same time. Also when you manually turn the dome lights on from the inside everything works perfectly. There is no fading here. It's on or off and you can keep pushing the button and it switches back and forth perfectly and instantly from door assist to regular lighting setting. I believe when I press the unlock button on the fob everything works also because I believe there is no fade in at that point. I could be mistaken on this. If it fades in then I probably have the same issue. It's something with the fade in signal that is making things weird for the coil to be activated. The BCM must be effected somehow as the dome lights flash on, off and then on same as the relay coil. It's like pin 23 is on then off then on. If there is no fade everything works perfectly. If you or anyone out there is good with circuit design please let me know if you have any suggestions. I would really like to get this last little bug worked out. Thanks all!

Holy cow.........triple post. Sorry. That was weird.

Double post.

I went with the quad square rounded tips also for the same reason. I'm pretty ocd when it comes to lines. The OP's round tips do look sick though!

So I am so close, but not quite. Everything works great except when you open the door the dome lights and relays flash/actuate 2 times then stay on. This was a circuit I created. My DPDT relay will be here today and that is the relay/circuit that mandrewbot3k said worked great, so I will try that today if I have time. I have a very busy weekend. I will post back results after I try it.

Just wow!

Thanks! I thought I was going to save you some money if you went the Borla route, but the sale unfortunately just ended at the end of July. I just happened on that site when I was looking for cat back systems. EDIT: Oops sorry, lol, thought you were the OP. I actually looked into just getting a Borla muffler instead of the whole cat back, but I called Borla and the guy told me the only option for my truck from Borla was the whole cat back. I looked into a lot of different options like Flowmaster, Magnaflow, Gibson, etc.

I had a Flowmaster on my 2008 Ram Sport and it droned. Was cool the first week or two and then it was annoying. Just did a ton of research over a weeks time and ended up getting the Borla 140780 Touring exhaust. I went back and forth a few days between Touring and S-Type, but after reading countless posts and listening to the Borla sound/videos I decided to go with the Touring. I absolutely LOVE it! Nice deep sound. Just sounds so badass without being obnoxious. If my truck was a fun 3rd vehicle that I didn't have to drive then I would have went S-Type, but as a daily commuter and 2 family trips per year I went with the Touring. Just put 1000 miles on it from NY to OH and back. No issues.

Got my Borla exhaust from https://www.autohance.com/ This is the exhaust I ended up going with. https://www.autohance.com/borla-140780-touring-cat-back-exhaust-system.html Dang it! Sale just ended. Bought mine for 1280 +tax free shipping.

Thank you for the explanation! My circuit ended up being a hybrid of the 2 circuits mandrewbot3k created. I used 2 relays to create a DPDT relay. I also ordered a DPDT relay, but using the 2 readily available relays with pigtails is more convenient. If I run into any issues with my current circuit I will try the single DPDT relay, but don't see how that would be beneficial at the moment. I did find some new 50v 220uF and some 25v 150uF caps, so I am going to try the 150uF and I think that will work. There was minimal relay buzz with 2 47uF (94uF total), so 150uF should do the trick. I will post back tonight with the results.

The circuit works! I just need to get a 220uF 16v+ capacitor. I thought I had more variety of caps than I did. Hopefully I will have one at work. I had two 47uF 50v caps I ran in parallel, but it was not quite enough to stop the buzzing. Close though. Everything else worked great! I'll try and draw up a halfway decent schematic tomorrow and post it.

I have been doing some research on this and it appears you can use 2 SPDT relays to create a DPDT relay as mandrewbot3k posted as being the best result. See the pic above of the single DPDT relay. Not only will this give you best result (according to mandrewbot3k), but it will also use relays that are readily available vs having to order (in most cases) a DPDT relay. I am using the SPDT relays from amazon that come with pigtails, so if one ever happens to go bad it can easily be swapped out. It really shouldn't take any longer to build as there are already pigtails and you would just be connecting the 2 coils together. I will be trying this tonight and I will update this thread and post a schematic if it all goes well. Relays from Amazon https://www.amazon.com/dp/B01KVZ2MU4?psc=1&ref=ppx_yo2ov_dt_b_product_details

Thanks for the reply. I may have figured out my issue. I won't be able to try it until after work today. It appears the diode in the schematic I followed is reversed for what I would need. I am not sure it will trigger even if I change the diode, but I will try. I am just not good enough with electronic circuits to know. I am attaching 3 pics of circuits I have found. The colorful one is the one I first found and followed with what appears to be the diode reversed. Everything works as it should with this circuit except the door trigger. The other 2 I found on this forum last night. In both of these the diode is the reverse of the colorful schematic. I did bench test the colorful schematic with a battery and everything worked as it should except I was using ground as the door trigger, where as pin 23 is not a ground trigger. Any input you could give me on these schematics I would really appreciate! Thanks!

Hi all, I am hoping someone can help me. I have a 2020 Silverado RST and have recently purchased an OPT7 Aura Pro interior lighting kit. I am having trouble with the double relay setup. I found this thread: Smoothbassman figured out a double relay setup that allows this system to function as it should. Unfortunately there was never a schematic provided. I found a double relay video and schematic on YouTube for the OPT7 Aura Pro kit, but unfortunately again, after I built the circuit it didn't work with the dome lights. I believe this is because it was designed as a dome light ground trigger and pin 23 for the dome lamp on the Silverado is not a ground trigger and does not actuate the relay on my circuit. I am not good enough with electronics to design a circuit and figure this out, even though it seems fairly simple. If anyone has installed the double relay with OPT7 Aura Pro could you please share the schematic? I would REALLY appreciate it!!!
