I have a 2000 maxima and I want to install the Commando EZ-2500. I would have to buy the transponder bypass correct? And do the maximas have positive doorlocks? I will be installing this myself, first install.

 

yes you will need a bypass. No they are negative pulse. Trunk release will need a relay. Make sure you connect Both starter wires.

 

a 30amp realy good enough?

 

30 amp relay will be fine.

if connecting both starter wires together, run through a diode.

 

Why ?
