Great item
Great item make sure you bolt relay down tho cause heavy vibrations cause it to act up just a bit but overall a great item

This fixed my problem
92 integra would randomly not start. I wouldn't drive it anywhere being afraid I would be stranded. This took 5 minutes to replace original and now it starts up every time.

Bad relay
Harness is well made, but cheap relay. If you tap the relay with your finger the car dies. Buy a proper bosch relay and pair it with the harness
