Looking for advice on running a battery kill switch for a crx. Battery is relocated to the trunk already running a odyssey battery with 0 gauge wiring. Looking on www.xenocron.com they have a 200amp solid state relay along with a metal rotary style switch + remote terminals. Would this be suffice to be legal at the track? Would run the battery positive/alternator to 1 side and the other side would run 1 wire to the fuse box. and then I presume the switch wires to the 2 small points in the middle of the relay. the switch will be mounted on the rear tail light and labeled.

Does a fuse need to be put in any place? or any extra wires ran to 1 or the other points on the solid state relay? And with the remote terminals I am intending on putting them on the outside rear near the switch which will be under a drag wing but easily visible/accessible. what gauge wire should be used for the remote terminals though and how should they be wired to the battery?

 

From my understanding of the battery kill switch, the solid state relay is for use with batteries that are mounted to the front of the car, and it allows you to install the NHRA compliant switch to the rear using small gauge wires. with that said, I have my battery mounted in the trunk using only the switch and no relay. One wire running from the starter to the switch, another wire from the switch to the alternator, and a wire from the switch to the battery. No fuse inline with any of those wires. Of course, I ran all the heavy gauge wires inside the car to a firewall bulkhead. Wiring it like this will kill all power to the front of the car including the engine because it kills the alternator. Edit: this is all done on the positive terminal. You can still install the solid state relay to avoid drilling large holes to run the 0 awg wires.
