93max

i have a 93 se. i have a cheap alarm (call ultra pro immobilizer makers of "the club")but all i bought it for was keyless entry. i heard that the car has a negative pulse system. it says one wire goes to +12v lock and and another goes to +12v unlock. the ground goes to the chassis, right? also can the parking light wire be hooked in the steering wheel column also (red and yellow wire)? thanx for any help
