True MODS 12V Automotive Waterproof 5-Pin Prewired Relay Fuse Box Block Kit

Very well made fused relay block. Unfortunately there was no place to mount for my application. I would most certainly buy again if the application were different.

REbuilding an old CJ5 and upgrading all electronics. I wanted something that is tough, waterproof, and performs. As others mention, the build quality is great. Glad I went with the harness version as the wires are all sealed very well. I love that this has individual power leads and also has individual wires for each relay pin so you can decide to wire using power in to trigger or use a ground wire to trigger. Really happy with this purchase.

I PURCHASED THIS ITEM AFTER MUCH RESEARCH. NOT REALIZING I HAD ALREADY PURCHASED TRUE MODS PRODUCTS IN THE PAST WHICH WERE EXCELLENT PRODUCTS. I FOUND THAT THIS ITEM WAS THE SAME QUALITY. THE MATERIALS USED TO MANUFACTURE RELAY SYSTEM ARE OF THE HIGHEST QUALITY AND BUILT FOR HEAVY DUTY USE. ONE THING I LIKED THE MOUNTING BRACKET IS METAL AND NOT PLASTIC LIKE NEARLY ALL THE OTHER RELAY SYSTEMS ARE MADE WITH. ALL LEADS ARE NUMBERED WHICH MAKES FOR EASIER INSTALLATION. THIS WAS A NO REGRETS PURCHASE!

I found this to be very well constructed. Base is of heavy plastic. The wires nicely organized and labeled. Easy to install, but you must have a basic understanding of automotive wiring and relays. If you have that, you will be golden. Instructions are also very good.

This is a great relay box. I gave a 4 rating because instructions & the items supplied in the cardboard box don't agree. Here's what was included in my purchase on 5/25/25. A black plastic relay box having a lid with o-ring gasket. The box has six 30/40 amp relays installed. Each relay is feed by an 11 inch long wire. Wire size TO relay contacts is 12 AWG. Wire FROM relay contacts is 12 AWG and is 11 inches long. Wire to and from relay coil is 16 AWG and 11 inches long. Included are 6 blade fuses installed in the relay box plus 6 blade fuses packaged separately. Total of four 10 amp fuses; four 20 amp; two 25 amp and two 35 amp. There is a single lug terminal (0.320 hole) connected to six 12 AWG wires which are 6 inches long. There are four non-stainless bracket mounts with 4 sets of stainless bolts, flat washers and nylon locknuts. There are 6 butt connectors for 12 AWG wire. The instructions are readable and very understandable. Each red power supply wire going to the box is labeled for the relay it feeds. Each relay has 5 wires leaving and each group of 5 is labeled as to the associated relay. Note - the clips holding the cover are difficult to release.

Super great relay! I had one of the tabs on the front cover break and they sent me a new one. I would definitely buy from this seller again!!!

Excelente producto. Llegó muy rápido.

why was this not an optional part popping up when I searched 7 months ago trying to build all this with no automotive electrical knowledge at all? For that also I didn’t have to buy the relays cause my switches can handle the small amps that even large led lights put out. Its the guys who run 6 accessories through one switch on the oem pulse bar that wander why battery is dead and stuff burns up. Throw a bone to us unacknowledged thank god I have a mechanically inclined mind with resources figured it out.
