I'm wiring my car alarm and my truck has positive door triggers and my alarm only has negative trigger inputs... What do I do about this?

Your alarm has a wire for positive door trigger. Tell us what kind of alarm you have and we can probably tell you what color the wire is.

If brown is siren, and green is negative door input, and blue is negative input for sensors, Violet should be positive door trigger.

Still no luck :( I tried hooking it up to the dome light and the door triggers from the door itself am I doing it right?

Which wire of your alarm do you have connected to the Siren? What color? I am not so sure that your vehicle has positive door triggers. Can somebody confirm?

Nope, it does not. It will have negative door triggers. Yellow/black for drivers door, and gray/red for passengers door.

Yeah and whenever I hook the door triggers up to the blue wire (with a diode) it goes off when I have the door closed and goes silent when I have the door open

the dome light is the easiest way to do this on a ranger. i wouldn't bother with independent door triggers. do you have the install manual for your alarm? if all else fails you can go to a shop and buy a small relay to switch the polarity of the door trigger to work with your alarm.

I bet I can hook up independent triggers, faster than you can run to a shop and buy a "small relay" -------------

i can hook up independent triggers faster than you can. we're not dealing with a pro here, so i was just giving options. you never know, his doorpins could be fudged. you should make sure you have a sharp knife before you try to stab someone with it. -------------

Is that kinda like bringing a knife to a gun fight...? Those vehicles seem to not work very well...I have seen alot of problems w/ the fords(dome lights and truck bed lights staying on)...Normally just some WD_40 works great...

Ok I have another question the car alarm says to hook up a wire to the accessory and it shows a key and ignition so I'm guessing that I need to hook it up to the ignition but idk which wire to use
thank you

you have to connect this to a true ignition wire in the vehicle, using your meter at the ignition harness meter the wires, this wire will read 12 when you turn to the on position and remain at twelve or there abouts when cranking and after the vehicle has started. this wire must never drop to zero while cranking.

oh and by the way as soundnsecurity said, the dome is easiest here, you won't require any relays to switch polarity either, it's straight negative trigger.
