These 5 pin relays work great
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.

Works great, directions are poor
The way the directions are worded is confusing. I used these to switch circuits for my boat. I ended up just using the schematic on the relay itself. Once properly wired, they work great, and you can't beat the price!

relays that actually work out of the box
Used these for some LED light work on my truck and every single one worked perfectly with no surprises. The wiring diagram printed right on the relay is super helpful when you're doing your own install and don't want to keep looking stuff up. Having the harness included means no splicing which saves a ton of time and makes the whole thing look cleaner. Really solid kit especially for a 5 pack at this price.

Toyota starter relay replacement
Perfect replacement for Toyota starter relay. A year after my 5VZ swap on my 1989 Toyota 4Runner (5-speed/manual transmission/previously 3vz engine.) I started getting a "click no start" issue. New battery and checked EVERYTHING prior to finally testing the starter relay. Installed another used OEM Toyota relay that started doing the same thing. Added this relay with an inline fuse and hasn't given me an issue over a year. * *Blue wire is power wire on the relay, soldered the inline fuse to the blue wire, soldered a long wire I got off a parts truck, crimped a ring terminal on the end and hooked it up the positive terminal of the battery. Even ran my wires thru the male side of the old relay connector to give it a factory finish/look.
