hey, I have a ford with the 1-wire door lock system,and im going to use this diagram from the12volt when i hook up my alarm next week. http://www.the12volt.com/doorlocks/page2.asp#fp

I was wondering do i have to use 5 way relays ? cause i have so many bosch 4 ways just sitting around in a box..Also are 30/40 amp relays good for this? and should i use a 10 amp inline fuse from radioshack or something higher? let me know thanks.

originally i was going to build a circuit board with to mini 10 amp relays but i dont want to do that anymore..
