Great fuse. Save your ECM/PCM in automotive use
Great relay. The flyback diode makes me feel a bit safer as I am triggering off my ECM to power a higher voltage accessory.

Best relay you can buy, built in diode too to protect sensitive electronics in your vehicle.
These are the best automotive relays you can get. They have built in diode protection too which most people aren't aware of. This is extremely important if you use these for adding accessories to your car.

Fast shipping. Correct product
It didn't solve the issue I was trying to fix on my 92 Volvo 240, but I don't think it was the relays fault. Shipping was fast and I received the correct relay that I ordered

This is the REAL BOSCH RELAY
Everybody makes a relay in this configuration, many of them are of marginal quality. Hard to know if the spin-offs are made as well, or better than as a Bosch. So, I like Bosch Relays. These are the real deal, they are BOSCH Brand.

It Works
Needed the relay for the light bar on my truck. It's been functioning well for months now, I usually have one blown every month or so. SO far this one is working out just fine.
