Review: nice little harness - got 3 of these to wire up an analog way of getting the radio in my truck to stay on till the door is opened. my only beef with this is that 3 of the wires are around 8 gauge, and 2 are 10/12 gauge. not a huge issue, and it's meant for wiring up lights and such, but in my case i wish i had known before hand. the socket is really snug, which is nice, i was worried it would feel really cheap, but it's the opposite. the wires themselves are probably around 10" long, so plenty long enough to splice into/ wire your own whatever with. UPDATE I did find one issue with these actually. when i first got them, i plugged them all into the relays to make sure they were snug and everything, then i put the project on a shelf until i finish another one. well, I was diddling with them and noticed something. I can NOT for the life of me get them OFF the relay! I tried prying, I tried pulling, I tried wiggling. these will NOT budge. Now take that as you will, I will never worry about these falling apart on me when I stick them in the dash of my truck, but if the relay takes a poot, then it's going to get intresting Review: Perfect for my project - I decided to install factory power windows and mirrors in my 2000 GMC Sierra Sierra and this fit the bill perfectly. My truck already had power door locks so I figured after owing it for 12 years, it was time to switch over to all power for everything. Instead of hacking into my factory circuits, I purchased an auxillary fuse block and fed the power window circuit and power mirror circuit through that fuse block. I used this relay pigtail with a 40-amp auto-reset circuit breaker for my power windows and it worked perfectly. No way anyone would ever look at my truck and think it didn't come from the factory with power windows and mirrors. Thanks Parts Express and desertcart. You made this project easy (and it all worked without any issues at all). ## Features - Socket for Bosch 5-Pin Relays: 12V DC Compatible - Pre-wired Socket for Bosch 5-Terminal Relays - Power Wires: 12" (14 AWG), Control Wires: 12" (18 AWG) - Easily Connect Multiple Sockets: Interlocking Sides ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002ZPUMG | | Best Sellers Rank | #272,265 in Automotive ( See Top 100 in Automotive ) #139 in Car Amplifier Power & Ground Cable #244 in Automotive Replacement Pigtails & Sockets | | Brand | Parts Express | | Coil Voltage | 12 Volts | | Connector Type | Plug-In | | Contact Material | Copper | | Contact Type | Normally Open | | Customer Reviews | 4.5 4.5 out of 5 stars (633) | | Date First Available | April 12, 2007 | | Department | Automotive | | Is Discontinued By Manufacturer | No | | Item Weight | 1.76 ounces | | Item model number | 330-075 | | Manufacturer | Parts Express | | Minimum Switching Voltage | 12 Volts (DC) | | Mounting Type | Socket Mount | | Operation Mode | Manual | | Other display features | Wireless | | Product Dimensions | 6.1 x 4.3 x 0.7 inches | | UPC | 812227030360 844632030673 844632079528 | ## Product Details - **Brand:** Parts Express - **Connector Type:** Plug-In - **Contact Material:** Copper - **Contact Type:** Normally Open - **Mounting Type:** Socket Mount ## Images ![330-075 12 VDC 5-Pin Relay Socket For Bosch Type Relay - Image 1](https://m.media-amazon.com/images/I/614aGiZyvhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ nice little harness *by J***N on May 7, 2011* got 3 of these to wire up an analog way of getting the radio in my truck to stay on till the door is opened. my only beef with this is that 3 of the wires are around 8 gauge, and 2 are 10/12 gauge. not a huge issue, and it's meant for wiring up lights and such, but in my case i wish i had known before hand. the socket is really snug, which is nice, i was worried it would feel really cheap, but it's the opposite. the wires themselves are probably around 10" long, so plenty long enough to splice into/ wire your own whatever with.

You made this project easy (and it all worked without any issues at all). ### ⭐⭐⭐⭐⭐ Convenient attachment of a hard-to-connect relay *by B***R on December 24, 2012* I use form-C relays with this wiring harness for automobiles and security systems. For example, I use two in my car to activate a very loud, after-market, compact motorcycle air horn when the wimpy factory horn of my car is inadequate: one relay is activated when the horn button is depressed, to supply a new 30A feed with an inline fuse to the relay output, where the second relay switches between the factory horn and the new airhorn. The first relay is switched by the factory wiring harness feed to the original horn, which no longer feeds the horn; only the relay's NO output is used. The second relay switches that new higher-power horn power feed between the OEM car horn, using the relay's NC output, and the new airhorn using the relay's NO output; the control signal for that relay is the high-beam power lead that is near where the horns are mounted. This causes the OEM horn to be used by default, most importantly when it is sounded by the remote door lock/unlock system, but also in normal use. On the open highway when the high beams are active, or elsewhere when the light-control stalk on the steering column is pulled toward the driver, the airhorn takes over, providing a rapid way (with practice) to get the attention of a distracted adjacent driver (or one who is 'listening' to their in-car 1 kW sound system) when they would otherwise continue changing or drifting into my lane, causing a collision. Security applications often involve activating an external siren or light that requires more current than the basic security panel can handle. Thus a 12V relay is required. In some cases the fact that this is a connector for a form-C relay (i.e., with both normally-open and normally-closed contacts) permits a single power supply to be switched between driving an external siren/light when in the alarm state, and driving powered sensors such as outdoor long-range IR+microwave intrusion detectors during the normal non-alarming state, reducing the need for multiple 12V DC power supplies. ## Frequently Bought Together - Parts Express 330-075 12 VDC 5-Pin Relay Socket For Bosch Type Relay - BOSCH 0332209150 Changeover Mini Relay - 5 Pins, 12 V, 20/30 A - Single - BOSCH 0332019150 Normal Open Mini Relay - 5 Pins, 12 V, 30 A - Single --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/1298175-330-075-12-vdc-5-pin-relay-socket-for-bosch](https://www.desertcart.co.th/products/1298175-330-075-12-vdc-5-pin-relay-socket-for-bosch) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
