4 Pin 12V 30A Multi-Purpose Automotive Relay - Heavy Duty Standard Relay for Car Motor, Universal Replacement Accessory

4 Pin 12V 30A Multi-Purpose Automotive Relay - Heavy Duty Standard Relay for Car Motor, Universal Replacement Accessory

Q: Is this relay the same relay my 2004 Honda Civic LX uses that says 16z3a31a on it ?

I don't know about your particular car, but despite Amazon's recommendation that this part fits my car, it doesn't. And I am not the only one complaining that I purchased the wrong part for my vehicle, based on Amazon's assurance that is the right one. Hope this helps.

Q: Will these actually fit a 2014 Nissan Titan Pro 4x? I have bought some that said they fit my truck but they do not.

Prob not bud I found the same issue and never received a refund but they stated they would fit I purchased them for a 2002 Durango slt and they did not so I will advise to check for yourself the pins and the voltage or amps and make sure they match regardless of what Amazon says . Because they don’t know anything and this continues to happen ….

Q: Do these things last long? Or do they keep blowing and thats why they send 4 of them?

So far so good with mine. They live in the toolbox with the battery on the tongue of my trailer which sits outside.

Blades are smaller making loose fit

Blades should be wider so they fit tightly like factory so not to cause overheating of the terminals. They worked but concerns of loose fit.
