Pegasus Racing sells the OMP fire system. It allows you to route the lines wherever you want. There is a master ECU and two triggers. One for the driver and one for the emergency steward at the track.
They are affordable and work very well. I have dealt with plenty of them going off, saving driver and car.
They absolutely suck to clean up. Once water hits it, it turns into Studio54 foam party.
Costs about $300 to refill the bottle annually to comply with most racing regulations.
