OK I have been staring at this "worlds best DIY immobiliser" (https://www.highrpm.org/howto/immobilizer/page1.html) diagram for a while and feel like an idiot... i understand the basics about it but as far as the wiring, what are the arrows about on the end of several of the wires in the diagram?? i have all the parts necessary so if anybody can offer any suggestions about the wiring going to and from the DPDT relay i would GREATLY apreciate it! THANKS!!

I always thought the world's best alarm immobiliser was my old German Shepherd with the window sticker "His Bite is Much Worse than His Bark"

PS It probably is the best for the 8-10 minutes it takes me to bypass, make good and box up the car.

https://www.highrpm.org/howto/immobilizer/page1.html The arrows in question are the internal part of the relays that actually moves when the relay is activated. If the relay in the following picture were to have the arrows on it, the arrow would be on the line between 30 and 87A, pointing to 87A.

ehh alot of criminals dont have the common sense enough to bypass it ad for those that do, i am fabricating a metal surrounding for my underdash cluster with a decently thick sheet metal and screws that require a certain tool to remove. Thanks for shedding some light and posting the diagram "i am an idiot". pretty sure i got it now

If you use that setup you might want to use an ignition switched 12V line for the latching relay, otherwise if you forget to reset it (being a manual operation), it'll run down your battery from the draw from the relay coils.
