The fact that so many come in a pack gives me solace that if one fails, there’s still several to replace it. Worth the money Review: Heavy Duty, SPDT, "Type B", 14 volt, 40/30Amp relay. Read my review to see what Type B means (Pin Layout) - This is a nice heavy duty relay. This relay comes with no info. Most of the pins #'s are covered in adhesive and are difficult to read. So I will give the info here. Hopefully this will make your install easier. There are two types of 5 pin relays. Type A and Type B. This is a Type B relay. This is noted by the position of pin 30. I was able to determine this because, lucky for me just enough of the 3 was peaking out from behind the adhesive, to allow me to determine pin 30 location. It is sort of the key or primmer to decoding relay types. (12 volt planet has a nice article on 5 pin relays, if you want professional advice. I am just a guy on desertcart, so take my advice for what it is worth) So I am wiring a reverse camera for my 2009 BMW E93 convertible. It did not come with a touch screen head unit, it came with an old school unit with only the basic digital screen. I updated my car with a 7 inch sat/nav with HD screen. Even though this car has pretty good visibility, the screen has backup camera capability, and desertcart offers a pretty cool back up camera that integrates into the tag light. So I figured why not. Well the reverse light is not a constant 12 volt, so I needed a relay to provide constant 12 volt power to the camera, and I use the reverse light as the on switch. My set up: Pin #30...constant 12 volt supply from a fused 15 amp supply line connected directly to my battery. BMW puts these in the trunk, right next to the tail light I am also tapping. (thanks BMW, easy peezy) Pin #85 Ground...attach this to any ground lug on the car body Pin #86 Switch source... for my BMW this is the black /violet wire to my tail light Pin #87 the red wire on my camera *****Some relays switch position #85 and #86, but form what I understand this is immaterial, because it is just either end of a switch, and so they are reversible, but your application may vary. THe pin positions for #85 ad #86 are unreadable in this relay. The wires on this relay are much heavier gauge (12 & 16 gauge) than the 15 amp circuit I am supplying or the 2 amp draw I am using. But that is to be expected from a 40 amp relay. Just know when you buy butt end connectors, you will need them to fit a heavier gauge. Or by pass the wires and buy 6.3 mm female connectors to connect directly to the relay pins. This however will bypass the waterproofing built in to the male portion of this relay, with the actual wires on it. ## Features - User Manual available for download under Product Information Details - Waterproof construction & heavy duty 12AWG wires for the main contact. - Bosch style 5-Pin SPDT (Single Pole Double Throw) Relay. - 12VDC (14V Max) and 40A/30A High Switching Capability. - Wire Specifications: Black - Ground (85), Red - VDC (30), White - Trigger (86), Yellow - Output N/C (87a), and Blue - Output N/O (87). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N66W2XF | | Best Sellers Rank | #10,378 in Automotive ( See Top 100 in Automotive ) #4 in Automotive Replacement Starter Relays | | Brand | ONLINE LED STORE | | Brand Name | ONLINE LED STORE | | Coil Voltage | 12 volts | | Connector Type | Solder | | Contact Current Rating | 40 A | | Contact Material | Silver Plated Copper | | Contact Type | Normally Closed | | Current Rating | 40 A | | Customer Reviews | 4.6 out of 5 stars 1,511 Reviews | | Item Highlight | Waterproof, Interlocking Harness Socket, 12 AWG, SPDT, 30/40 Amp, 12 Volt Automotive Relays, For Auto Car Truck Fan RV | | Item Weight | 3.84 ounces | | Manufacturer | ONLINE LED STORE | | Maximum Switching Current | 40 A | | Minimum Switching Voltage | 10 volts_of_direct_current | | Model | SUVELAM | | Mounting Type | Surface Mount | | Number of Items | 1 | | Operation Mode | Auto,Manual | | Part Number | PSZACCEPS177R | | UPC | 816165023866 | | Wattage | 14.4 watts | ## Product Details - **Connector Type:** Solder - **Contact Material:** Silver Plated Copper - **Contact Type:** Normally Closed - **Current Rating:** 40 A - **Mounting Type:** Surface Mount ## Images ![True MODS 1 Pack Bosch Style 5-Pin 12V Waterproof Relay Kit SPDT 30/40 Amp - Image 1](https://m.media-amazon.com/images/I/81m2P8Wl3RL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How many amps does it take to make the relay switch from open to closed?? I have a 1.5 amp circuit that I want to use as the switch power** A: The relay only requires about 150 milliamps @ 12 V DC to be triggered. Hope this helps. **Q: I am wanting to put in an on/off switch on a 4wheeler to the existing 12v dc auxilary jack. what wires would to to what posts on the 3 prong switch?** A: It would be better to run a new fused feed from the battery and use the accessory wire from the key switch so you always shut it off and not forget and run your battery dead. **Q: Im noticing a constant buzz from my relays. What could be the issue? Bad switch? Bad ground? too much voltage drop?** A: Are all the relays that are buzzing connected to the same trigger switch? If so, the trigger switch may be supplying power (or ground) to the relays even when in the "off" position. This is only one possibility. The relay itself may be faulty, just the likelihood of multiple units failing at the same time is slim. Please contact us directly to further troubleshoot the matter. Thanks. **Q: I am hooking up a amp to a mototcycle, the instruction says i need to use this. Why?** A: HOW MANY AMPS DOES YOUR AMPLIFIER DRAW..... IT MAY NEED ITS OWN CIRCUT BREAKER FED THUR THIS RELAY, BE CAREFULLY YOU DONT BURN THINGS UP, USE THE RIGHT SIZE WIRING AND PROTECT WITH THE RIGHT SIZE FUSE ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth the money *by A***S on January 1, 2026* I was skeptical but it seems to hold up pretty well.

I put it in my 2017 Superduty to run my auxiliary backup lights with my upfitter switches. With this relay installed I can run the auxiliary backup lights in two modes, ON when ever I want (even with the truck OFF) or make them go ON and OFF with the factory back up lights. Works great and I didn’t have to use a diode. My configuration uses two of the upfitter switches in the truck. The mounting bracket worked out nice. This relay is water proof as well, has a nice ribbed torturous path gasket. 7/16/20 Update: Two years now and still working, no issues. Thumbs up! 7/25/2023 Still going strong! 05/21/24 still working!!! I bought two of these on my original purchase, one as a spare because that’s what I do. The spare is still sitting on the shelf in my basement. ## Frequently Bought Together - True MODS 1 Pack 5-Pin 12V Bosch Style Waterproof Relay Kit [Harness Socket] [12 AWG Hot Wires] [SPDT] [30/40 Amp] 12 Volt Automotive Marine Relays for Boats Auto Fan Cars - 12 AWG Inline Fuse Holder - 12 Gauge Fuse Holder for 30A Blade Fuse (6 Pack) - 10 Gauge Fuse Holder - 10 AWG Inline Fuse Holder with 40 AMP ATC Blade Fuses (4pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/36964846-true-mods-1-pack-bosch-style-5-pin-12v-waterproof](https://www.desertcart.id/products/36964846-true-mods-1-pack-bosch-style-5-pin-12v-waterproof) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-09-29*
