30A Power Cable with Relay, Direct Wiring Harness This is a direct wiring harness with a 30A relay. It's a cable set purchased from Autobacs, and I believe it was made by Aimon, but I'm not certain. For stable power supply to high-output car audio, navigation systems, etc. Relay: 30A specification Slow-blow fuse: 30A Power cord: 3m It was working without any problems until recently. I am selling it because I am replacing my system. Please feel free to ask if you have any questions. Thank you for looking.
