Figured I would share my setup on the newer (2025) Cartek X-Club Battery Isolator and how I got it setup so that it might help future 86 track people pass tech.
Thanks to @
RedReplicant for sharing his setup. Greatly helped me get mine installed.
Hardest Part IMHO is getting that darn fuse box open. You have to disengage all the tabs on the sides at the same time and pull up. Once you have access to the bottom side of the fuse box you want the White/Black wire going from the IG2 Main 30A fuse to the IG2 Relays Pin 5.
Splice it at an even length and run some 14 awg wire from the two leads you created out the back of the fuse box near the big bundle; please crimp and shield all connections you make.
Since I like the idea of having the fuse between power and the ECU I opted to wiring in a 30A 4 Pin Relay to cut the power between IG2 Main and the IG2 Relay. The Cable from IG2 Main Fuse wires to PIN 30 on the Relay and PIN 87 on the Relay goes to the IG2 Relay Pin 5. The Engine Stop signal from the isolator is wired to Pin 86 and Pin 85 gets wire to a chassis ground.
Mount your external kill switch they provide to some place you want it ; I chose passenger side on the plastic cowl panel near where I planned to mount the isolator. Run the wires to the internal switch they provide ; mount where convenient or based on org rules. (Just remember the internal switch Black to Black and Red to Red as it has a light).
Prep the mounting area so the isolator makes good contact with the service, I drilled out 2 holes to mount some bolts through the firewall which you can reach from the inside from behind the dash amazingly; assuming you have all the ac stuff removed. Mount the two free grounds to the mount points. Make a battery negative cable and attach that to the isolator.
Make sure all your cables are ran and protected. Attaches the positive battery terminal and then the single battery negative connection and you should see a blue status LED.
Test the system out for any faults.
This was probably super clear based on Carteks instructions to some folks, however, sometimes I need my hand held
I hope this helps others in the future.
