H'i, I recently installed an Omega Excalibur 1850 in a 94 Nissan 300zx!! When I installed it I had the alarm and remote start working perfectly!! I also wires the door lock relay and diode circuits but there was an issue with the cars factory lock system that I told the guy he needed to get fixed for the keyless to work correctly through the omega system so he did and got the locks working but then the alarm stopped completely and it's very possible he just has it stuck in valet mode!! But this is the first Omega system I've ever installed so before I go back down there to figure it out I just wanna get other ideas!! Remote start and keyless now working perfectly just no alarm functions!! Won't trigger on any some not even doors or hood and yes the hood pin was installed!! I soldered all my connections and tested with a DMM all suspected wires in car!!! Anyway any and all info would be greatly appreciated!! So hopefully I'm not spending all day trying to trace this problem out!!!
