This thread is still a work in progress, but I just added lock/unlock info to this post, and door open/closed trigger info in a reply below.

It's a Viper 5901.

Original post here :


I found this site useful when installing

I decided to place the brain below the storage pocket in front of the shifters. There's barely enough room, but with enough cramming, it fits.
There were many unused wires coming off the Viper harness. I bundled them up about 6" away from the connector and ziptied them together.

Pull the stereo out, and the drivers side panel in front of your knees, and the steering column cover. You should be able to do this all with a #2 and #3 philips. I also took off both the kick panels and removed the glove compartment, but don't know how necessary those really were.

For power, use an 8-9 gauge wire directly from the battery, fused close to the battery (50A) like for a speaker amp. Ran it through 3-4" grommet passenger side footwell, to a power distro block to the 3 power wires for the rem start. See pic at bottom. Arrow points to the grommet I poked with a box knife to make a slit then shoved the power wire through with needle nose pliers. Stuff it until it stops, then go inside the cab - I'm 2 for 2 on being able to reach wires when I used this method, but I suppose there's a chance it will get hung up on something and not come down from where the grommet is.

For ground, I used a bolt that holds the t-case shifter down.

At steering column, hooked both ignition and starter wires together with the output from the remote starter. I think there are two of each to carry twice the current without increasing the wire size of a single wire.

Quick-tap into the brake wire above pedal.

Parking light output connected to wire under steering column cover. See pic for the area I tapped into.

Hood switch - Use wire 6 at the SECU. Gives a ground when hood opened.
Neutral start switch - hook to a ground.
Remote start enable switch - connect and run to footwell but secure switch just behind the edge of the panel so you have to reach behind to flip it.

Pulled the a-pillar off and stuck the antenna right above the rear view mirror with the wire going right into the headliner. Ran wire down a-pillar through the brackets Nissan nicely put there for me, and tucked into edge of dashboard.

I didn't use the siren because I was only concerned with the remote start. I hooked it up temporarily for programming options because it chirps a certain number of times to indicate which menu you're in.
Programming - you have to set it to "automatic transmission" mode; the default is manual. (if you have an auto, of course.)

See my reply below for how to hook up the door open/closed signal.

For lock, give a ground to SECU wire 10 (Yel/Red).
For unlock, give a ground to SECU wire 11 (Yel). May require a double-pulse.

Wire for park lights is in here, where the blue quick-tap is:

There are three wires that give a signal which indicates a door is open. Front left, front right, and all 3 rears. They output a ground when a door is open; 12v when closed. To connect all three for the purpose of triggering the alarm, they must be isolated via diodes. I built the board below (pic) to achieve this, for under $5. The board is a radio shack 274-678 european style terminal strip. I think the diodes were 1N5399-S Silicon Diodes (3-Pack)

The inputs will need to be connected to the wires at terminals 1 (Grn/Red), 2 (Grn/Black), and 3 (Red/Blk) of the SECU.

If you're not familiar with diodes:
Since it's passing a ground, the diodes go in backwards compared to how they would be oriented if it were passing +12v. You can think of diodes as "positive current flows + to - from black to white". Ground flows from white to black. See the pic of my setup and you can see the white end of each diode - it appears gray in the pics)

Thanks for the writeup and the links. I got the 5901 and tried to install it myself. But when I try and initate the remote start it says "Remote Start Error" and then gives seven beeps/flashes. According to the manual "7 flashes: manual transmission mode is enabled and not initialized." I'm not sure what exactly this means. I have tried it with the switch in both positions and my neutral safety switch is grounded to the center console/radio frame. Any thoughts?

Edit: I just reread your post. How do I set it to automatic from the default manual mode. I wasn't able to find it anywhere in the users manual. I've held the 'F' button for 8 seconds and gone through the menu to no avail.

Nevermind. Figured out how to set it to automatic. I reread the manual and realized there's two sets of menus. The one I was accessing before was just for the remote. There's a much larger set of menus for the security system and remote start.

That being said. It now tries to start, as in the starter turns, but the engine doesn't turn over. It just stops the starter after about 2-3 seconds and tries again in a few. Any thoughts?

Did you connect both car-side ignition wires and both car-side starter wires together with the one from the remote starter? There are a pair of each running up the steering column, and they both need to be connected to the remote starter's power wires. i.e. cut both starter wires and splice the 4 ends you just created, with the starter wire from the Viper.

Also, check that the truck still starts as usual with a key. At one point during my install, I was baffled that nothing happened when I tested the remote start, but then I realized I didn't reconnect the ignition harness...

The first thing I did was check to see if it started with a key. Which promptly set off the alarm lol. But yeah, it starts normally.

I think I just have the starter wire on the brain connected to one starter wire on the column because the wire colors were different than your '02 guide so I wasn't sure of the 2nd starter wire. You think this could cause it not to start? I suppose one method to check would be to cut one of the starter wires (if i can find it) and try to start the car normally and see if it has the same sound/effect. Thoughts?

That would be a good test to see if my suspicion is correct. Both pairs of wires must be connected.

Did you do the door locks/opening connections? If so, care to share some info about how you tapped into the wires at the SECU cleanly? (pics?) It's such a cramped area I gave up for now. Ideally, I'd have a jumper harness to go in-line with the connector, but don't know what the manufacturer/part number of the connector is.

Your second starter wire on your '01 should be green/yellow. This wire trips the cold start injectors, so it needs to be hooked up also to start correctly.

Also check that your tach signal is good and that you have it programmed to the brain.

Both can cause it to crank, but no start.

the link is not working anymore.. can you fix that for me or redirect me to one... and one more thing can you explainthe diode a littlebit more... im heading out tomorrow to pick that stuff up from radio shack

The diodes take the three door inputs and connect them to one output without connecting them to each other. I'll type more later when I'm at a computer

Sorry for the delay; I was out of town and typing on a touch screen isn't much fun.

Diodes are one-way streets for electricity. In this case, the three wires you'll tap into at the SECU are passing a ground signal, so the diodes are installed "backwards." The purpose of the little diode board is to make an output if any one of the three door-open signals is given. I believe they're 1)driver's door 2) passenger's door 3)any other door.

You don't want to just twist the three wires together without this diode separation; otherwise you'll be connecting them to each other.

I did not need an extra relay; the remote starter I have is designed to provide a second output for vehicles like ours. See if yours lists that feature before going through the expense and effort of setting one up.

I can't fix the link. They seem to have "updated" their web page and removed it. I might have saved it; if I find it, I'll let you know.

i have the clifford 50.7 and if im not mistaken its the same as your alarm... i will pm you my number and get with you if you dont mind.. that way you can answer some of my questions if you dont mind... between you and creepy i think i might be able to get this installed by myself :)
 
#14 ·
any idea where i could get an install Manuel for my viper 5701? ive googled my butt off, im still left a little confused on how to do it all.
 
#15 ·
i used epoxy rectifer diodes will that be a problem?

The other option you can do is use the dome light wire as a door trigger wire. There's downsides to it (alarm will beep twice saying a "door" was open, but will still watch the trigger after the dome light goes out.. or as it thinks the door is closed)... but has the advantage of not requiring the use of the diodes for those who aren't use to using them

Ok, here's a really really crappy ass picture I sketched out to represent what the diodes are doing and why they are used. I *hope* at least one person looks at it and goes "oh, I get it now!" (which means my picture can actually be followed! lol)

Image


In the picture above, you can see the "one-way street" a diode provides. If you want to know exactly how a diode (and transistor) works PM me lol

Image


Here's a sketch of the wiring for a 2004 Xterra door pin setup. I put a blue line (with crappy arrows to show which way the +12V is heading) to show where the voltage would want to flow from and to if you didn't have diodes installed (IE, just hooked all three door pin wires to the door trigger on the alarm brain) and opened a rear door. WITH the diodes in there, the blue lines would STOP at the diodes, so you can see how it allows the alarms trigger wire to ground to the door pin, BUT keeps the OTHER door pins from also grounding out.
