installed new o2 sensor in exhaust and when i was going to connect the wire to the wire that goes into the engine.. the wire female clip that goes into the engine broke, so now im stuck with a short little o2 wire from the engine.. anyone knows where that wire goes to, and if so how can i attach the o2 wires together.. cause right now running without the o2 sensor wires connected.. basically the wire that the comes from the engine to the exhaust o2 sensor wire the connection is broken.. pics would be helpfull.. tried looking at wire diagram.. dont understand it.. help..

well if it's just one wire essentially that's broken, you can solder in some jumper wire.

You can solder the O2 sensor wires directly w/o a connector. Sorry I don't have any pics to tell you what goes where, but maybe you could try the FSM in the FAQ.

In the meantime you can run just fine without the O2 sensor. Its purpose it to carefully balance fuel and air for optimum gas mileage and emissions. I hear you lose about 2 mpg without it.

i would like to solder the wires together.. only problem tho is that the wire that goes to the engine is soo short, that i can barely get a hold of it.. if anyone know where the wire goes to and maybe i can pull it back to the harness and just rewire it there, like add solder some inches to it or something.. some pics would be nice if possible.

Got two pieces of wire that are too far apart to attach together.

So, put a female connector on each of those two pieces of wire.

Now get a piece of 18 to 22 gauge wire long enough to reach b/t the two ends where you just put a female connector.

Put a male connector on each end of your new piece of wire.

Mate the females to the male ends. Done. A complete circuit.

Or get a piece of 18 to 22 gauge wire to bridge the gap b/t the ends that won't reach each other. Solder the new wire to the old wires. Done. A complete circuit.

I'd recommend solder and heat shrink wrap. It's more secure, and you can still get it all at radio shack pretty easily. I do find that those old wires can get buildup on them though--some good soldering flux (removes impurities) helps the wire to take solder. Sears has some Craftsman liquid soldering flux.

Strip back a lot of insulation off that short end of the wire. Then take a good length of new 18 gauge wire and strip the end off, and now twist the two ends together. Apply a little bit of flux to the connection. It's a lot easier to keep them together if you took off a little more insulation. Get yourself like a 100 watt soldering gun down there and place it under the joint.

Let it heat the thing up for maybe 20-30 seconds. Then apply the solder (get a spool of thin stuff) to the wires themselves--not the tip of the gun. Once the joint is heated up enough the solder should flow right in... let it flow in evenly and don't overdo it. Then get the heat shrink wrap you bought and thread the other end of the jump wire through it until it's over the solder joint. Heat it up for a few seconds and it will contract over the joint, providing more secure coverage than electrical tape.

The goal here is to extend the short end of the wire first. Then you can put quick disconnect terminals on there or whatever you want to do.
