Total newbie here!!! I was wondering if someone could help me with a question I have. I would like to be able to power my underbody neons by either using a switch that's in the car (it's a lighted switch), or by the aux. button on my remote starter. I believe I would need to use a relay...but I'm just not positive on how everything would hookup. I'm attaching a diagram below...if someone could tell me how I would go about hooking this up I would really appreciate it. I wasn't sure if I would also need to use diodes?
I added the wiring to your diagram
the "aux" on your remote starter is probably live only when the remote starter is running the engine. as soon as you turn the key, the remote starter shuts off (and shuts off the "aux" function as well). if it's independent of the starter itself, then you may be able to use it. just wire the "aux" (+) output wire to lead 86 of the relay.
Here is how to Properly Wire it up with both alarm and Relay.
When Fusing make sure you put the fuse as close to the power source as possible. You should be able to use a fuse inline that is the same Amperage as the one on your D-block.
Good luck, hope this helps
EDIT: Diodes in diagram are in reverse bias by accident intall in forward bias
AND your Acc wire off the switch should not be connected to the 12v input (line over extended) this will completely bypass your switch
Thank you sooooooooo much! I really appreciate that!!!!
OK, I have this setup like the picture shown below and I'm able to turn the lights on and off by either the switch or the remote. What I was wondering is could this setup be modified so that if I turned on the lights by the switch, I could then turn them off by the remote (and visa versa)?
If anyone has any idea on this, I'd appreciate it. :-)
You would need to change the switch and relay to SPDT types and then wire them in series. At present you have just SPST types in parallel.
