Good quality. Works well.

The prewired harnesses didn’t have tinned wire so I kept looking for one that I could wire myself. These were perfect, the connectors that came with the kit were tinned. The bottom of the plug has a fairly thick silicone gasket that you run the wires through. The connector that goes to the relays also has a gasket. I will be using these to replace the corroded connectors for my power trim.

What more can you ask for? Most relay sockets come with some wire. This requires you to have splices or have where your going with the wire very close to the relay. With this wire the way you want to. Great price, quality product.

Used these under the hood to kick on my KC lights when I energize the high beams. Wired the coil terminal to the high beam power wire. Comes with a nice tab bracket for mounting.

Overall this gets the job done, but minus one star for poor and potentially project-wrecking instructions, and minus one star for the oversized terminals for the coil wires.Instructions:The instructions given are unclear, and since you don’t get spare crimps, can really screw up your project if you do things in the wrong order. As stated the instructions are:Remove the 4-hole blue pad from the socket.Put the wires through the holes.Fix the wires to the terminals.Put the terminals into the socket from the bottom.Reset the blue pad.I don’t know why they included “from the bottom” in step 4, it implied to me the terminals came up from the bottom side of the connector, which they do not. The correct order is:1) Remove blue pad2) Insert wires *through* blue pad3) Insert wires *through* the bottom of the housing (from the “blue pad” side to the “relay side”)4) Crimp terminal to wire and then push terminals down into the housing so they click – be careful about pulling on the wire if you have any doubts about your crimp – getting the terminal back out of the block to re-crimp is nearly impossible.5) Slide the blue pad back up into the bottom of the housing to seal6) Seat the relay to the housingCrimps:As others have noted, the kit comes with 4 identical crimp terminals, which are all 10-12 AWG sized. I was glad that this relay supports 10AWG wire for the power end – too many kits are advertised as “40A” relay harnesses but come with smaller (12 or 14 AWG) power leads. However, unless you use massively over-sized wires for your signal lines to the coil, you’re going to have some trouble getting a solid crimp.The seller advises to strip extra wiring and fold it back. This *may* work, but the key thing is to use a crimping tool that will “dimple” the folded tabs. This ends up taking multiple tools and multiple steps since you have to manually begin folding the crimp tabs (needle-nose pliers?) then use 2nd tool to get a good tight crimp.

I haven’t had a chance to install them yet but they seem to be decent quality relays. They have a decent amount of weight to them and the weather seals seem to be a decent quality silicone. The crimp conectors supplied seem to be good quality but like the others mentioned it would be nice to have smaller crimps for the trigger wires. The main reason I bought these particular relays is because the 5 pin model showed to have the resistor built in to prevent high voltage back feeding to the power source when the magnetic field from the coil collapses. Upon unboxing and inspection I noticed the schematic did not show this resistor on my 5 pin relays. I will use these for circuits that wont be affected or damaged by the mag field collapsing. If your needing a good relay that has the resistor or diode to prevent feed back, HELLA makes it both in 4 pin and 5 pin models, spst, spdt, ect. Overall I’m happy with them. Good product and good price. I’ll update this review after I get them installed and have some hours on them.

Needed waterproof relays to wire into existing harness. Did not want it prewired. These are perfect

The base is too tight when putting the relay on it and hard to push together enough for the clip to lock together. Very hard to separate the base from the relay. Also I ordered a 4 pin and received a 5 pin relay.
