Is this wiring correct? (DIAGRAM PICTURE INSIDE)

Hey everyone, I'm trying to hook up strobe lights to my car and i want the strobe lights to come on with my alarm when it's going off and i would also like to be able to switch them on manually for shows. The unit its self would always to ON so that it would light up the strobes when my alarm is going off. So to do this i understand i need relays. I have used two relays in my diagram to control the siren and the switch. "X" is the power sent to my strobes when the switch is bridged, as well as when the siren is going off. "V" is where i plan to hook up the power wires from the siren and the switch. The switch and siren would not be simultaneously used as there really would not be a reason to but would there be any detrimental effects by doing so? Last but not least here's the diagram i did up on paint, please let me know if there is anything wrong with it or if there is something else i could do to make it a better setup.

Hm

Interesting. Well, if you want the strobes to go off with your alarm, you will need to tap a wire into the security system. But then like another switch or something so it could be turned on manually.......Im confused.

Well i do have a suggestion. You might want to hook up your wires to the postive jumper terminal located in the upper left hand area under your hood. That is what people usally do to wire angel eyes.......

i don't see why you would need 2 relays. i'm sure you can do it with just one 5 pin relay. one pin for power, one for ground, one as a trigger wire from the alarm (when it's going off), and one more from the power with a switch going through it.

Yeah you're totally right! i was just on google searching relay diagrams and i just just figured it out before i read your post, thank you though. All i need to do is connect the two pins (87 and 87A) of a Bosch relay to the strobe light unit and have one with an on/off switch.

What fuses do you think should i use for the power wires? 10A?

depends on how much your strobes and alarm draw. just find that amount and buy the next amperage for the fuse. that way if you have even any spike, it'll blow. make sure your wires can withstand it as well. i don't want you melting your wires before the fuse blows lol

Ok I think you have the relays backwards. If the + and - on your diagram signify the "coil" leads then you basically don't need the relays because they are going to be always on....

you would want to use relays when the trigger source can not provide enough current to power the additional strobe lights....

So I would use one relay for the alarm but have the positive lead you show coming off of the siren go to the positive lead of the relays coil, and the power from the battery go to where you have the + lead from the siren in your current diagram.....

and if you are just going to use a switch for like shows and stuff you don't need a relay for that, just a switch that is rated high enough current/voltage wise to handle the draw from the strobes.
