Automotive Relay Harness Set

These 5 pin, 30 amp, relays are well made and always good to have around. I have some spares and will use them on future projects. The wiring diagram printed on them is easy to understand and straight forward for the novice.

Used two of these to make reversible DC motor control for continuous operation Definitely Excellent Value

So far I’ve only used one wiring up a fan and it’s working flawlessly.

Bought 2x 5 packs of the relays and found that 1 was bad right out of the box. Replaced it with another that I bought. Spent a bunch of time troubleshooting what was wrong before finding the relay issue.

I used these to wire some auxiliary lights on my car. They do what they are supposed to do. I don't detect any flaws or weaknesses yet after two months of use. Seem legit.

The price is certainly right! What I like about this product is that it includes the connection socket with colored wires. What I found difficult with this product is that the connection socket slots are not perfectly aligned to accept the blades of the relay assembly. (It appears the socket was assembled without care). If one attempts to insert the relay assembly with force, it will damage the socket since not all of the blades line up to the haphazardly assembled socket. One has to first carefully match the relay blades to each slot in the socket by slightly bending the ones that don't fit precisely. Then the relay will insert without damage or difficulty.My brother's Jeep has messed up wiring in the low beam headlight circuit somewhere in the wiring loom. We used one of these relays to just rewire the low beam circuit to go around the bad wiring. The relay is controlled by the regular low beam switch on the steering column so the car still functions as if its original wiring was still in play. (We disconnected the original wiring from the low beam light filaments and replaced it with the output of the newly installed relay)! So far, it has been working perfectly for the past 2 weeks! What is still a mystery is how long will this relay continue to function seeing as it is from China?As an aside, one should 'cap off', (or at least tape off), the end of the unused red wire. It is a funtional wire connection to the relay that is not normally used.

Relay itself seems ok, but the wires & connectors are way too small. Relay is rated for 30 amp load, but wires got very hot & connector SMOKED with about 15 amp load. Yes, actually smoked with less than 3 minutes of use, which did not blow a 20 amp fuse. So the wires and connectors are completely insufficient for the rating by half.I can't use that, so I returned for refund. On the advise of my EE neighbor, I went way bigger & bought a bigger relay with stud terminals. So the big wires can connect directly. That is working out much better.The bigger relay I bought is the [Hamolar 2 Pack 12V DC 120A Starter Relay Switch Car Heavy Duty Split Charge Continuous Duty 4 Terminal SPST Relays for Truck Boat Marine] https://amzn.to/3QmpFkh
