What type of alarm are you installing? What year is your car?

its a python 3000esp. i have a 92 sc300

933005spd

Virtually every wire you will need is located on your factory alarm ecu. Do you have a wiring schematic for it? If not, I can get you a copy from my 93 manual which should be the same.

I presume you are installing yourself? Do you wish you use the existing key to disarm (use the OEM alarm to turn the python on/off) - not recommended. Or are you going to just disable the OEM system - recommended.
