THE INSTALL BAY Metra E-123 Tyco Relay 12 Volt 30 Amp Each

I bought these to replace the relays in my Ford Truck aftermarket headlight harness. The original relays were sticky and soon the high beam relay failed. Since I put these in, no more stuck on headlights and everything is back to normal. Build quality looks excellent. If I need more of this type of relay, these are the ones I'll be getting.

Direct replacement for a surprisingly hard to find relay at a decent price. Plugged into the harness and worked right away. Need a few more of these so will purchase again.

Used this relay after a cheaper one blew. So far it has lasted and has worked every time. The last one used to get 'stuck' sometimes so my foglights wouldn't go off with high beams but this one clicks every time and has yet to miss! Would recommend and buy again (although I don't think I'll have to!)

For $5.00 I fixed a very complicated stereo system in my boat. The system was put in before I bought it, and all the wires are deeply hidden and buried, and very hard to work on. So when I traced the problem to a 20 year old relay, and was able to buy 2 replacements from Amazon for less than $10.00, get them in 2 days, and then install one and fix the stereo, I was very happy.

There's not a lot to say about this one. If you know what it is then you should know how it's used. I keep several on hand, I always seem to be adding lights to my vehicles. Buy the plug for it insead of using individual terminals for a much cleaner install and no hassle reconnecting it when you have to replace one. Instead of wiring it as the diagram shows you, consider connecting the switch lead to 12+ and putting your switch on the ground terminal. Done that way you only have one wire to run to the dash and it's a ground, not hot. Connect the other side of your switch to any convenient ground. Much safer and simpler.
