I just bought a new daily driver and it came with an alarm/remote start that I would love to put in before winter. The car is a 2003 Mitsubishi Eclipse GS with a manual transmission (no factory alarm) and the alarm is a Viper 5706v. It came with a few extras too the guy said I would need to install it. Some sort of key bypass (dei 556u) and a battery back-up (dei 520t). It also came with a glass break sensor (dei 506t) and a 2 smaller piezo sirens.

Well I went to the local audio shop and to hook everything up they quoted me like half of what I paid for the car! Lol So I would like to try and install this myself. I’m pretty confused to be honest. Lol Mostly on what wires I need to be using from the alarms harnesses. Like I’ve found most the wires in my car already at the ignition and above the fuse box that I will need to use. I’m mostly confused on which wires from the alarms harnesses I need to be hooking up and which ones can I de-pin. I know alot of the wires won’t be used so if someone could help me with which wires I could just depin and get rid of all together that would help a ton. That way I can focus on what I actually need to be hooking up and start from there. I attached a couple pics of the alarm wiring diagram and my cars wiring diagram. Thanks for any help in advance!

On the main ignition harness all the red wires are 12v input, pink is ignition out, green is starter in, violet is starter out, and orange is accessory out.

Thats what the manual says too, my problem is I don’t know where these are supposed to connect to in the car though. I guess I just dont understand the terminology. So do all the fused red wires just go to a constant 12v? Because I thought they each got hooked up to different ignition/accessory wires for their 12v.

The green and violet wires make sense (connect to each side of my black/red (+) starter wire at ignition harness)

But then I also don’t understand what the orange and pink wires do exactly. You say pink is ignition out and orange is accessory out. So do I just connect the pink wire to my ignition 1 wire (green +) at ignition harness and the orange wire to accessory 1 wire (blue/red +) at my ignition harness?

Defrost is yellow/red at the hvac controls. It is a negative trigger. The diagram doesn’t show if it’s momentary or latched so you’ll have to test for that.

I have no idea what any of this means. Lol I found the wire at the hvac controls but how do I test it to see if its momentary or latched? And how does it get connected to the alarm? Do just I just connect the wire to one of the auxiliary outputs on the auxiliary harness?

All the red wires will go to the constant 12v in the ignition harness.

Yes

Also, I think your car has a second ignition or acessory wire not listed it your diagram. You’ll need to connect it for the remote start.

Set your meter to the continuity setting. One probe goes to the defrost wire, one to ground.
Press the defrost button.

If the meter tones when you press the button, and stops when you release the button, it’s momentary. You’ll need to connect it to one of the aux outputs and trigger it manually with your fob after the car is running.

If the meter tones when you press the button and continuies even after releasing the button it’s latched. You can connect it to the -200ma ignition 1 output in the auxillary harness and it will turn on with the remote start..

Okay cool. Thanks man, you’ve been a huge help. The remote start is what was confusing me the most. On all those power wires on the r/s harness I thought they needed to go to accessory and ignition 12v by the way they are described in the manual. So I was really confused what to do with the wires that are actually supposed to go to the accessory and ignition wires! This is my first time even looking at a alarm so its been alot to take in. Lol

I think I’ve pretty much got all the wiring figured out now. Only question I have left I guess is whats the best way to give a constant 12v to all these power wires? I have 3 for the remote start, one for the alarm brain, and one for the 556u. Should I really go to the ignition wire for all of them or is there a better method? I’d like to keep it as stealth as possible. But it just seems like alot to try and attach 5 power wires to same wire at the ignition harness. Just wondering if there’s a better way to do it?

The 556u and alarm12v leads can be tapped into the red 12v rs lead between the brain and the big fuse on that wire. The other two 12v wires can be tied together right after the fuses on those wires. Then you only have two 12v wires to attach to your ignition harnes.

If you have more than one 12v ignition wire attach one of the rs wires to each 12v wire in your cars harness.

The ignition harness is already powering everything the RS powers, so there is not harm connecting the Alram/RS to it.

Alarms are just a deterrent to stop the smash and grab/crackead thiefs. Any thief that knows enough to get under the dash and disconnect this stuff is going to get what he wants.
It’s just a waste of time trying to get super creative hiding stuff, and it makes troubleshooting a nightmare if you have problems or want to add features later.

All your connections should be soldered, no butt connectors, no T-taps.
