what resistors do i need for my dome light and horn on my car alarm, and are there any other resistors i may need in the process of installing this remote start/alarm...I have remote entry if that helps?

whoa
I might suggest taking ur car to a pro.
If you don't want to do that, which i can understand, take your time to read up and learn. I personally learned all about alarms and relays and soldering and such for a couple weeks before I started.

What alarm are you installing???
You don't need resistors, but you will need some relays.
You will need them for your dome light and trunk popper (if you have one, and if you have the output for one on ur alarm). I'm not sure if you need one for ur horn because I used the siren that came with my alarm. If you are in fact using your horn, I would use a relay just to be safe.
I used SPST (single pole, single throw) relays (i think) but it's gonna be easier to just go to like www.oznium.com and pick up a SPDT (single pole double throw) relay and a harness that they sell. I wish I would have had the harness when I did mine. Makes it a bunch easier.

If you need anymore help, ask here or IM/Email me, info is in my profile.
