I'm on my second one going on the third. this one only lasted through one bottle. i know for sure im going to change up the way everything is wired. just wondering if anyone else had this problem and what you did to fix it.

 

How do you have it wired now? You shouldn't burn up relays, with less than 2 N20 solenoids.

Can I recommend this way... (for safety, remember to fuse it all w/proper sized fuses)

I have the relay for arming the system as follows:

power wire from the fuse box into arming switch(in the interior) then to the wot switch then to the relay for switching(also powers window switch) . a wire from the battery to the continuous power output of the relay (to solenoids)<im going to be hooking that wire up to the switch in the interior for arming the system as well as the switched power incase the relay gets fused thereby locking my soleniods open. the grounding wire from my window switch creates the ground for the solenoid relay also.

 

never had a problem with mine, if you are drawing the rated current or lower the relays should last. You should draw what you have and post it, not sure what you are saying 100% by your description. Your NX kit should have came with a wiring diagram, make sure it's wired up like that and you should be good to go.
