Great affordable improvement to my vehicle

My 1994 Astro van that I have owned since new would burn out the A contact of the igntion switch when I put the rear a/c fan speed on high and it occurred to me several times so I added the BIR80 relay and it was a great improvement. This or the BIR200 would work well for fire or police or first responder vehicles that have light bars and radio and computer equipment that demand high currents. https://www.youtube.com/watch?v=qpU8vKmVj4g&t=137s

It works.

It does what it’s supposed to do, handles rated power no problem.

Works.

Works good. I was sent the wiring diagram for the 200 amp version, otherwise all good. It does make noise “clicks on”. So if you are going to use it for in cab car audio etc, it will make noise when clicks on. It works with stereo remote.
