12V+ I see this on all Wiring Diagrams, this means to connect 12 volt Positive to it,

and Always constant,,always metering 12 volts,car on or off??? I've seen it for my door locks, alarm,starter

Relay, and lots of other relay diagrams, If this is so Can I connect them all to the same sources?

In all the Vehicle Info, sheets I've look at I see CONSTANT 12V+ can everything be connected to this?

This Forum is incredible Mark

hey there, the 12 volt constant means there is a constant 12 volt positive signal going through that wire regardless weither the key is on or off, it's the same as hooking it direct to the battery, and as long as the wire is a heavy enough guage to support the extra load you can put what you need on this wire, if it's not heavy enough guage and you put to much load then i'm gonna assume you know what can happen posted_image

but when i install a remote car starter or alarm i put the 12 volt power wire to the constant 12 volt wire in the ignition harness. all it means is that it's a constant source for 12 volt.

I tought so ,thanks for confirming this,I hope there was others-who weren't clear.

anyway wheres the best place to install the alarm mainframe, yo you keep the relay in the same place,

It seems like there a lot of connection at the ignition Harness or fuse box.it just seem like you need allot of room, to get everything in the same place. My Alarm and door lock units pulse all the wires looks like it will take up allot of room. is there a rule of thumb on placement of different Accessory ? do you cut short all the wires that you don't connect,roll'm up and zip tie, its got to be neat and out of site

This site the best.Mark
