True MODS 6 Pack Bosch Style 5-Pin 12V Relay Kit [Interlocking Harness Socket Holder] [14 AWG Hot Wires] [SPDT] [30/40 Amp] 12 Volt Automotive Relays for Auto Fan Cars

Electronic items can be a gamble when you go cheap. I was afraid that purchasing these at this price would not yield good results. The positive reviews definitely bolstered my belief that I'd be fine, but after installing 5 out of 6 relays I am a believer. I would not hesitate to purchase these again. Matter of fact, I am likely to get more of these in the near future. Great item! I used these relays in conjunction with a keyless entry module to install in my older vehicle that did not come with keyless entry. Long story short, I wanted to separate the driver's side door power lock motor to be isolated from the other door locks in order to have it unlocked separately. These relays helped to separate and isolate the driver's side door lock motor. They have been working for over a week with no issues. Based on other reviews I have no concerns that these will not continue to function as they are suppose to.

This is the third time I’ve ordered these, and they work great! The sockets have what appears to be 14 gauge wires for the coil, and 12 gauge wire for the contacts. The sockets interlock, allowing the user to chain as many relays as desired together. I use them to make converters for trailer taillights.

The leads are just right for interconnections between relays. These are good enough for simple 12v prop building for haunted houses and escape rooms. The interlocking harnesses make assembly organized. I so far used eight. I would buy again. If you use these with switches and LEDs to indicate the state of the switch, use switches that are ON ON, not ON OFF ON. With a 3 position switch in the off position floating and a relay set to a negative trigger, the LED will light. With a positive trigger, a 3p switch and LED behave as expected. In either configuration, the relays perform perfectly.

I ordered these for a project car. I will say you get what you pay for. The work as they should, but the wires are loose in all of the connectors which bothers me. Could make some issues down the road, but for now they operate as should.

Work as expected

I have used 2 of the pack so far, and the wiring and quality is very good so far. As i always do, make sure to use some diaelectric grease on the exposed wire terminals on the bottom of the relay socket, and you will be good for a long time. Not sure why Amazon asked me to rate the "Sheerness" of the product, but i guess they are very sheer? LOL!

In my home automation setup, I turn my landscape lights on at dusk and off at dawn. Because I installed it 20 years ago, it is still using x10, not the most reliable. So I wanted to set up a feedback circuit so my controlling computer could tell if the lights had come on or not. So I bought an AC to DC converted (so my landscape power would be 12 volts DC) and connected it to the relay. Connected the normally open contacts to my digital input on my home controller, and now I can tell when the lights are on! If they don't come on, the controller sends the "turn on" command again and again until the lights DO come on. Works very well, so far. Some documentation I saw was a little confusing, as in one place it indicated that ground should be in one pin, and other docs indicated it should go on another pin. but as this was for the NO and NC contacts, it didn't matter, as they are independent of ground. Only needed one of these (but now I have spares!). Nice little bracket that came with it, so I could mount it to a post outside, out of sight.

Really nice kit. Everything that you need except wiring connectors and wiring diagram. Easy to find diagram online. Made wiring my cooling fan very easy.

a must for hotrod projects these are a good unit

Work great clip together well and easily hid under battery tray.
