Relay for Interior Neon

ok you want to take a wirer from a constant source of twelve volts and run it to pin 87 now take another piece of wire and conect pin 87 with pin 86 yes conect bothe pin 86 and pin 87 together.

now pin 85 will be going to your negative door trigger.

pin 30 will go to your neons positive laed

now about that switch you want to add well conect one wire from it to pin 87 and

connect the other side of the switch to the wire coming off of pin 30

and heres how it will work when the door is opened in the car pin 87 and pin 30 will connect turning on the light and when you shut the door the light will go off but when you flip your switch you added it will come back on and stay on till you turn the switch off.

i hope you understand if not i will draw it for you ok good luck.this is probably the least complicated way of doing this that is why im telling you do wire the relay this way good luck,hope you get it .

Ok, I got one more annoying question, cuz my electronics knowledge has decreased. I know you mentioned using a diode for something, where do I put the diode and how do I line it up (with the positive and negative). And I bought diodes that can hold 12V, so should that work? Thanks

you dont need a relay just add your switch, send a good source of power like the battery to it ,use a 14 gauge wire ,or maybe a 16 and wire all the neons to the switch .neons dont draw much current so a relay would be added work for you .make sure you use a good quality switch one that can handle maybe 10 amps to be on the safe side if you add more neons at a later time. now just ground your neons and your lit. good luck
