This model does NOT come with the factory installed hood pin switch. I purchased the OEM pin switch and installed it. I am not sure if it will work though or if it needs some additional wiring. There is a wiring harness sitting at the hood release to open the hood that was meant to be plugged into the OEM hood switch. I connected it. Still unsure if that is all that needs to be done. Does anyone know if that will work? If not, I assume I will have to run a wire and install a regular hood pin switch. Another question is, on the immobilizer unit BLADE-AL, there is one wirte that says "without OEM hood status only" and a symbol for ground I think. Would I use this wire to run to the pin switch if the one I installed (the OEM) one does not work? What happens if I do nothing? Will the RS still operate and just not turn off if I open the hood or does this wire HAVE to be connected?
