The shock sensor install was harder than expected. I tried wiring the power to the orange trunk wire but was difficult since the splicers I bought were meant to be used on thicker guage wire. Either way, I ended up using the normal power in the back of the fuse box like everyone else...but the sensitivity of it is NOT good enough! I mounted the shock sensor to the ignition cables but even though I shake the car, the sensors still dont trip. I know 100% they work because I can be inside and tap the sensor and it'll trigger the alarm. Where else have you mounted the shock sensor so that even a cat can set it off?
