Uh for higher draw items (20-30A+) DO NOT SWAP 30 AND 87!!! The way the switch works inside, power flows from 30 to 87. Reversing that flow especially something powered on for longer periods of time and/or higher draw (20-30A+), leads to a quick death of the relay due to power surge each time it is powered on. Short term it will work but long term will die early.
I like how u explained that wires can be switched around between the pins. There are 2 circuits in that particular relay. Each one has a power in side and a ground side. The relay doesn't care which direction the power flows so its ok to switch the wires on their respective circuit pins. The low power circuit is the coil and power can come in on either side, all it does is create a magnetic field that pulls the contacts of the high power circuit together to allow power to flow thru. Again, it doesn't matter which direction. Excellent video thanks.
Can I copy your setup step by step if I’m hooking up to a factory aux switch? So instead of the last wire to your switch it would go straight to my aux switch? Is that right?
Correct. Just be sure your factory AUX switches are positive. In some rare cases manufacturers use ground. Some people wire their relays to be triggered by ground.
If it is the same Ford relay I'm thinking of (I haven't used in many years) the pin number conversion would be; 1=86 (+ from switch) 2=87 (+ to light) 3=85 (ground) 4=30 (+ from batt.) I would do some bench testing with this because as I said, I haven't used one of those relays in years. I hope this helps, thank you for watching!
Love your videos. Is there a link to wiring up my wiper motor to my Chevy express. I have a 5 pin relay, an on/off toggle with 3 pins on the bottom, an inline fuse and wire. I need help bc it’s not working. Ty
Hi just saw this video and I think you can help me out, I have a ultrastart 1250 keyless entry/ auto start lately the lights don't flash when locking/unlocking and dash lights don't come on when I autostart I checked all fuses and theyre fine. I can hear the clicking in the truck when I unlock lock and auto start like always, anyhow I contacted another UA-camr and was advised " while running wire use a neg out instead and add a inverted relay"- I have very limited experience and asked him to explain it to me in laymen's terms o haven't heard a response. Is they're anyway you can help me out and explain what I exactly have to do?
They can, but I recommend the Red (main power for relay) to come from the battery as it will have the most power/current being drawn through it. The Orange would be no problem in the fuse panel. Thanks for watching!
Thanks I just wired a bulbs great and clear video for new learner.only thing I would like to know how to adopt it to a vehicle without using a switch so it come on when ignition turn on.
Hi bud I have a ultrastart auto start/ keyless entry system the lights stopped flashing when I use the auto start or unlock door, I was told the relay was blown can I just get a new relay and plug it back into the module?
do you have to use fuses if you are using something low power draw and wiring to dome lights that already have fuses? Im trying to use this relay to activate some led lights from a dome light that is negative switched.
If you know how many watts your lights or accessories are you can calculate it. Just divide your total watts by your voltage. This will give you your amps, example; a pair of 60W lights, 60X2=120. 120W÷12V=10. This is 10A. Be sure to give yourself some wiggle room, with 10A I would us a 15A Fuse. I hope this helps!
great info.. question for pin 86... I want to hook up a relay in my car to light up LED footwells. can I hook up my door sw + wire from my fuse box to pin 86 as the trigger ? and pin 30 going to my LED footwell .. so when I open the doors the LED Footwell lights come on ?
Thanks for the video so the switch needs power, but im confused if i am using a fused relay panel how do i get power to the switch again? This is what im doing see the link but what do i need to add to power the switches? ua-cam.com/video/BvFHA1xY10w/v-deo.html
The fuse for your switch is always going to be a small one, something like a 3 or 5 amp fuse. As for your accessory, you need to do some simple math. If you are wiring up a light that is 100 Watts for example here is how to figure out your amps. Watts divided by Volts, we have a 100 Watt light and the average vehicle puts out 13.8 Volts when running. 100/13.8=7.246, call it 7.25 Amps. Now you know how many amps your light is, just give yourself a safety zone when picking a fuse. With a 7.25 Amp load I would use a 15 Amp fuse, a 10 would be okay, but your Amperage can change with your voltage, so a 15 would be best. I hope that answers your question, thanks for watching!
Is there a reason to not use a micro relay?? Like parts availability? Longevity of relay? Overall just curious af to why use these over big 4 pin relays
These are typically only 4 pin most of the time, so if you needed a 5 pin these wouldn't work. Availability like you said, you normally won't find these in the local auto parts store. As for the life of them... I've had some in one of the Jeeps for a few years now with no issues. Some companies rate these up to 40 Amps, I wouldn't but anymore than 20 constantly through them, so I would say these are a slightly lighter duty relay. You can fit a lot more of these in a compact space over the standard Bosch style relay so I would say that's the biggest plus for these.
I'm not sure about the relays AND fuses in one when it comes to the micros. There are some when it comes to regular relays, some regular relays even have fuses built into them.
I love micro relays. I started using them recently with littlefuse fuse boxes to update vintage car wiring to a modern relay based system. you can really pack a lot of these into a really small footprint which I like.
The multiple wire colors is going to confuse people that aren’t somewhat technically savvy and for those of us who are it’s just annoying. I appreciate your time and effort and the production quality was great but if you would have just used red and black wires it would have simplified this greatly. Red and black wire from the light go *here* and *here*/red and black from switch go *here* and *here*. Hell you could’ve even said red and black go from these two pins to this certain place/ red and black go from the other two pins to these certain places. Easy peasy. Thanks for the video. It was informative.
Thanks for watching! I use all the different colors for when people ask me for a diagram, it is much easier to follow colors on paper rather than a bunch of red & black lines on paper.
I was stumped on the part where the switch need power as well lol! Thanks for clearing up everything!
Glad to help! Thanks for watching!

This is probably the best explanation about wiring a relay that I've watched. Thank you!!

I have some ford 4 pin relays that have 1 2 3 4 instead if 30 85 86 87 so how do i wire those 4 pins for my 52 inch light bar ?
If it is the same Ford relay I'm thinking of (I haven't used in many years) the pin number conversion would be;
1=86 (+ from switch)
2=87 (+ to light)

I love relays if i can use it I will. Low voltage high voltage or low voltage controlling a higher power so many activity's haha jus love them
How do I know what size inline fuse to use?
If you know how many watts your lights or accessories are you can calculate it. Just divide your total watts by your voltage. This will give you your amps, example; a pair of 60W lights, 60X2=120. 120W÷12V=10. This is 10A. Be sure to give yourself some wiggle room, with 10A I would us a 15A Fuse.

its a smaller relay but irs the same function?
Absolutely the best and most explicitly,explained in its entirety for the first timer,,,good job mate !!!
Lol this video stopped my truck from catching on fire, you’re a stud.
That great info Rocky! I like watching your wiring videos
Thanks Chad!

Thank you sir i have done more videos but not yet understand all about, bcoz of your explanation tutorial is now completed thank you
Very very helpful !
Thanks.....I know you spent a lot of time to make the vid clear and understandable
Great Video Bro. you made it easy for people that would never try to wire a light this helps and makes it easy to understand. Thanks
Thanks!

@@RockyXTV good deal! Do you know of any boxes that house these relays and fuses together? I gotta make a common source for 7 harnesses.
I'm not sure about the relays AND fuses in one when it comes to the micros. There are some when it comes to regular relays, some regular relays even have fuses built into them.
@@RockyXTV i found one. It uses a 280 series relay. Bussmann 15303-2-2-4 is the part number but bussmann makes several versions and styles
Ahh... I have seen these, but for full size relays, never the micros. Thanks for sharing!
YOU ARE THE BEST... I TOTALLY UNDERSTAND....GOD BLESS YOU
Thank you very much!
