2002 Honda Odessey, remote start

I've looked at a couple of sources and don't see one either.  Maybe it arms with lock?  Never done one of these vans, so I'm not sure.

I've done a bunch of those, as well as my mother's 2003......and thanks to this forum, I managed to get her factory keyless to stay working with the remote start running.

Anyway, here's a basic wire-location shortcut list:

--Ignition wires: Easy enough to find, in black tubing coming down the steering column.
If you want the radio to remain off during remote start, don't make any connection to the WHITE/ black (or is it WHITE/ red?) accessory wire---it is not needed.

--Parking lights and brake: There are several plugs at the fusebox. RED / black is positive lights; WHITE/ black is positive brake.
While you're there, you can also zip-tie your programming switch to those harnesses-----it'll be easy to remember that you put the switch with the fuses.

--Tachometer: Remove driver's kick panel. Tach is a blue wire, in a light blue plug down there.

--Disarm-only: If you want to disarm the factory alarm WITHOUT unlocking the doors, you must find the blue wire INSIDE the driver's door. But that's the hard way.

--Doorlocks: Passenger-side fusebox, just above the fuses. I always forget the wire colors but I'm sure you guys can find a tech sheet somewhere.

Test these wires while turning the KEY in the passenger door, NOT by using the rocker switch on the door panel.

These wires not only control the locks, but the arm/disarm the factory alarm, and they turn on the domelight when you unlock.

--Disarm for remote start: Simple, as long as you bought good product with the right outputs.

Connect a "pulse before start" output from your remote starter, to the car's unlock wire.

Connect a "pulse after start" output from your remote starter, to the car's lock wire.

So, here's how it works: When you hit the remote-start button, the car unlocks and disarms the alarm. As soon as the car starts, it re-locks.

--Factory keyless with engine running: The factory keyless module is above the glovebox someplace. It's small, brown, and has the Omron brand name on it. It has just four wires.

The yellow wire should be ignition. Interrupt this wire during remote start, the keyless will not "know" that the ignition is on, and the remotes will still work.

Ultrastart units have a programmable feature that when enabled, it automatically unlocks, remote starts, and relocks; very easy to do, works for 04 grand prix's flawless

If you are not yet familiar with relays, it would probably be helpful to read up on them a bit---the Relays section on this site is very good.

You'll need to configure the relay so that the Honda yellow wire is "broken" when the remote start is on.......so you are basically "hiding" the fact that the car is running............and when the remote start is off, the wire should behave as it did from the factory.

You just need an ordinary, single-pole, double-throw (SPDT) relay, wired like this:

85: ground-when-running output from RS (That is, an output from the remote starter that puts out a negative whenver the remote starter is on)

86: FUSED, constant 12 volts

87: not used

87a and 30: Cut the Honda yellow wire in half. Connect one half to 87a, and the other half to 30.......doesn't matter which one goes where.
