We successfully installed the alarm and everything seems to be working fine besides the locking and unlocking functions of the alarm. The alarms arms/disarms itself but doesn't lock/unlock the doors.

Currently, we are using the pink/black for locking and yellow/green for unlocking.

The Viper 5002 uses a 7 pin relay wiring harness.

What wiring diagram do we use for the locking system?

We have already tried 12volt pulse driving factory relays, which blew the fuse on the harness. We also tried the negative ground pulses driving factory relay, which did nothing.

After researching online, I couldn't figure out the polarity of the locking system, are they negative trigger?

Should we use Directly wired reversing polarity switch circuit?

 

The keyless module is directly behind the starter button under the dash. On the top row, I believe, there are two empty slots side by side. These are the lock and unlock wires...or outputs from the module rather. All you have to do is add your own pin and wire. Of course you will want to verify this by way of multimeter, but they are regular negative triggers off the module. If you are going to the drivers kickpanel for the other wires you mentioned, they are also negative trigger. Either way will work...you can pull off the master switch in the drivers door panel to see the lock/unlock colors if you dont have a wiring schematic; or go to the keyless module as mentioned above.

 

I have been using the wires from the keyless entry module.

After looking at the Helms it seems pins 11 and 12 are not used. I am still confused at how I go about using these though, can you explain in more depth?

Thank you!

 

we have a 5 wire locking system youll need to snip your lock and unlock wires and use the 451m 5 wire relay that comes with the alarm. This is not just a simple 2 wire lock/unlock system.

you need to use the lock and unlock wires that come off of the factory keyless module.

Lock - Pink/Black

Unlock - Yellow/Green or Pink/Blue


and for the 5 wire relay

White/black to lock switch
Green/black to lock motor

Brown/black to unlock switch
Blue/black to unlock motor

And purple to whatever trigger you need (12v for positive trigger, ground for negative trigger) Try both, just have another fuse ready because i forgot if we use a neg or a pos for trigger.

 

Whoa...thats not correct. There has never been any honda that needed a 5 wire for door lock/unlock.

The wires off the keyless module, or lack thereof, are in two empty slots side by side. This basically means what it states...there will be two empty slots with nothing in them (no wires) that perform lock and unlock. I dont have my info in front of me, but from memory, one of the empty slots is beside a yellow wire. Its either a yellow wire with a black stripe---> or some other color stripe, *or* the stripe itself is yellow. My mind is telling me yellow/black. Anyhow, they should be the only two empty slots that are side by side on the upper row.

If you need a picture I can take one for you. Pretty much what I did on my last S2k was take two pre-existing wires with similar female terminated ends (from a HU's wiring harness, Sony I believe) and used them in the two empty slots spaces.

I had to use a small drill bit to enlarge each slot slightly, then fished the ends through the factory harness unplugged, connected each line to the correct male pin off the factory module and plugged the harness back in.

Again, if you need a picture I'll be glad to post it...or send it to your email rather. I forgot I cant post pic's without being a member.

 

while im not going to argue there MAY be another way to wire up the lock and unlock, your are incorrect saying there has never been a honda with a 5 wire lock. I have been doing installations for about a good 4 years now and i have done 4 s2000's. I have used the 451m 5 wire relay with all dei systems. Never had a problem. I have never heard of the lock and unlock working off of a 2 wire system.

now of course if this is something i dont know, definately i would love to know, it would speed up my installations by a good 10 min.

I am interested in seeing how you wired it up with a 2 wire system. please explain.

 

The only reason you would have to use a 451m or any relay for a 5-wire is if you go to the motor wires. All motor/actuator wires, excluding vacuum locks, are reverse polarity requiring the 5-wire. Since the S2000 doesnt have a dedicated lock/unlock button doing the 5-wire is the only way. However, there are negative trigger wires that can be caught in the drivers kick. I personally have never bothered to look for them, but others on this site say they are there. I have always gone to the keyless module and added my own two wires in the empty slots as mentioned above.

This is info I obtained years ago through DEI tech sheets and have used ever since. You can easily verify and test the two empty slots by rigging up a simple length of wire with a small inline fuse (always be safe). One end goes into the said slot(s) to make contact with the pin, and the other end to ground of course. When I first had to verify this info I clipped one end of my inline fused wire to the acc socket edge behind the e-brake (for ground) and slid upside down under the dash and just probed the two slots with the other end of the wire.

After that it was just a matter of having a small enough female terminated end to fit through the slot and snuggly enough over the male keyless module pin and thats it.

We always have some factory HU harness' laying around the shop(sony and jvc are the easiest to take the pins out of)...pop out two of the pins from the HU's harness, ream out each slot alittle so they fit through and crimp them down a tad if they dont fit snuggly over the factory male pin off the keyless module. All in all, after the first time of course, it usually takes me about 5 minutes to do.

So, in a way you are correct about the 5-wire, it can always be done...but I have yet to run into any honda/acura that didnt have some type of basic 2 wire negative trigger.

touche

 

ahhh touche indeed

i think ill stick with the 5 wire, im so used to doing it on the s2000, but i will definately look into that, because I never knew about that. I thought the s2000 was the only honda that had to use a 5 wire, but i guess wrong

thanks for the explanation i appreciate it, im gonna go check it out. after 4 years youd think i would find that out but all dei tech sheets i have used say 5 wire is required for lock and unlock on s2000 hmmm weird

and as for the OP, if you can do the 2 wire as explained by ishift@9v3 i would go that route, but if not ill be glad to help out with the 5 wire system
