I'll take a guess and say the longer goes after the cat and the shorter one goes before it. I might be wrong though.

Can't you see how your current O2 sensors are setup? Or did you remove them already?

The longer one is for the secondary O2 sensor. If you check the plugs on the ends they are specific to the location of the O2 sensor. So, if one plug goes to the bottom and the other the top then you know which sensor goes where.

Technically speaking the O2 sensors are the same...it is just the plug on the end which is different.

Splicing the wire is totally normal unless you buy your O2 sensor directly from an OEM Honda dealership.

Just make sure to use a good quality 16-18 gauge wire and solder the extensions on. Don't be tempted to just use wire nuts or electrical tape. Do the wiring correctly and you won't have to do it twice.

What shailoche means is that you have to solder the wires if you don't want to have problems in the future.

It depends what you want to splice to the O2 wires. If it's something that pulls a lot of current you might damage the ECU. I don't know the specifics but that's the general rule.

Is it a wireless solder pen? Those aren't too good and might create cold joints. It's best if you use a wired soldering iron that runs off the mains in your house.

Any reasonable 30 watt soldering iron will do the job. I too am worried that a soldering pen may not have enough juice to solder those 16 gauge wires. I would suggest getting a genuine soldering iron from HomeDepot or Radioshack.
While you are there get some good thick solder wire. That way you make sure that the joint is strong enough to handle the heat that will be created. If the solder isn't correct for the wiring it could actually melt under the high temperatures under the hood and with the current flowing through the wire. I have seen it happen. So, if you splice the wiring and it breaks apart go back and use a hotter solder wire and higher wattage iron to get you a stronger joint.

Good luck!
