I want to hook up about 8 pairs of strobes to flash when my alarm is triggered but i also want to be able to turn the strobes on whenever i want with a switch. This is what i plan to do and i just wanna make sure i got the wiring right. To have the strobes trigger for my alarm i'm going to run the power wire from all the strobes to the relay on my alarm ECU, i also want to splice the power wires to a switch so i can turn them on whenever. My question is can i splice the power wire from the strobes without affecting anything??

This is a little confusing.
Ok, you have strobe lights you want to hook up so when your alarm goes off, so do they.
for them to activate you need to have a signal wire that will kick them on when the alarm goes off. I would say use the siren as the signal, but every time you arm or disarm the car they are going to flash. (would get annoying)
The parking lights are not a constant signal so that wont work.
I am pretty sure there is going to be some sort of signal wire that you can tap into that will produce a signal only on alarm sound. I would use that as a signal and use relays for power.
the switch is easy. Just have a switch between power and relay.
If i misunderstood the question please let me know.

Run all the strobes through a relay. Run the relay turn on to a SPDT switch. Run continuous power to one switch input, alarm relay to the other. At the end you should have two ON's and one OFF, one ON for the alarm, the other ON for whenever you want to turn it on.
