I'm installing a crimestoppers sp-400 alarm/remote start/auto door locks system on my 86 camaro. There are two main power wires that come from the brain that need a 12 volt constant as well as several relays, like for the dome light, door locks, trunk pop that need a 12v constant also. I found the red 12v constant wire coming from the ignition harness, my question is can I run all my 12v constant wires to that? Will it handle it? Or do I need to run a wire straight from the battery to it? The instructions make it sound like your run it all from that red ignition wire but I wanted to be sure. Thanks!

 

look at your fuse box. theres several blank spots . some are labeled batt, some are labled ign, some are labeled lights, or radio. you can take a single male spade term, plug in there and run a wire to where ever you have the brain for the alarm and viola, youre done. batt terminals are 12v constant, ign is 12v switched, lights get power when you turn on the lights...you get the idea?
