For me, Waja. I think it easy to do it. Only Cost RM10~20.
Actually, you just need to buy some relay + wire, a switch that very flexible, Waja panel got 5 button, 1 disarm Alarm Siren, following with fog lamp switch then, emergency light then Heater.
I just need to find the disarm Alarm Siren switch panel(since i already change my alarm), and some wiring with relay, and i just pull my key to on, just press the button it started. I'll post my video afterward or tomorrow. Anyway, i wanna do something like 7Heaven does,
ACC switch, On Switch and Start Switch! wow! just like D1Spec! wakakakak
