How do the unused relay/fuse sockets stay waterproof? I only need 3 relays right now but want room for more.

All the seals for the bottom come without any holes, so there is no need to wire the terminals with short pigtails like another answer suggested. You need to actually poke a hole in them to wire it. The holes are already most of the way through, with just a little skin left at the bottom so it's sealed untill you need it. I just pushed a little dowl through the holes I wanted open for wire.

Can i use the fuses in the panel for the same circuit as the relays?

Yes. I used the fuses for the load side of the relays.

Does the kit with harness come pre wired?

Mine did not, but it came with all the clips and everything To go on the wires and then click into it. I used it for my UTV.. It is very nice. The one in the picture that you asking me about. Looks like it is pre-wired and numbered for each Relay.

Can I use one of these as a horn relay, grounding one coil through the steering column with three others supplied current from switches as usual?

A relay is nothing more than a switch with a normally open and a normally closed contact. Yes you can use a relay to energize your horn. The button in the steering column switches ground when you push it. Connect the ground potential coming from the closed horn switch to the relay on terminal 86, connect a constant 30 amp potential12V source to both 85 & 30 and connect 87 to the positive side of the horn. The horn must be grounded to function. When you push the horn button the circuit to the relay coil will close, switching it to energize the horn.

Q**E

Great product and very affordable!

This has been a great addition to my 1997 Tahoe project as an "aftermarket add-ons" relay housing. So far, I've used 3 relay slots for upgrading my upgraded side mirrors to turn the built-in turn signals into turn signal/running lights and 2 relay slots for the door lock actuator polarity swap in the aftermarket remote starter. There's one slot left with no immediate plans and I haven't used any fuse slots yet but I'm sure I'll come up with something lol. Overall, this is a great, easy to use product and it looks right at home in my truck. 10/10 would recommend to any intermediate to advanced DIY guy! Side note: It does come with additional terminal connectors but it still pays to plan all your wiring configurations ahead of time. My "shoot from the hip" method wound up costing me a few of them...

Decent Quality

Decent quality. It's really intended to be mounted in a panel - though they do supply some little legs it can stand on. In combination with some good quality (E.g. Bosch) relays, this is a good option for automotive / marine use.

Bien content de mon achat

Jai installer cette boîte dans mon bateau pour faire fonctionner quelques circuits, je suis très satisfait, bonne qualité et pas de pièces manquantes, peut-être difficile pour certaines personne sans expérience dans le domaine électricité d'auto.

Looks good, works well

Just installed it into a piece of equipment we built. Looks great and should hold up to water and prevent corrosion. Will update if I find otherwise.
