I bought a X3Racing header and right away noticed that the O2 sensor location in near the bottom of the oil pan on the header. The 2200's OEM location is right near the head on the exhuast manifold. Way too short by at least a foot.
Simple question, What are my options? I figure the simplest solution is an O2 simulater. But, if I want to run the O2 sensor, could I buy an extension harness to make it longer to reach? Or maybe split the loom bundle of wires to get some slack. I could always solder on a longer piece of wire, but that would be a last resort.
What are my options?
i know the pacesetter i just bought came with an extension kit...you will definitley need to extend the wiring for it.

cant use an O2 sim on the front O2, that O2's the most important of the two, you can get an extention kit that allows you extend your O2's wire.
^^ Where? Autozone, Advance?
i did an extension to my 2.4L and the car is running lean sometimes. and if i disconected it goes away but the codes come up and the car give me about 15mpg
but at least i got my response back.
i dont know how will it react on the 2200
I bought a 36" extension for $25 from Caspers Electronics. It was already pre-wired so all I had to do is plug the 02 sensor into it, then it into the wiring harness. I got it
here. No codes in the 3 years I've had my header on.
check with pacesetter, maybe they sell it seperatley

all you have to do is extend the wires. it will cost you like a couple bucks.
So, I could splice in a longer piece of wire if I solder and heatshrink it? What type and gauge should I use? Solid, stranded?

You should have never cut the wires on the 2.4 O2 sensor, it will always give your problems. There is enough extra mire in the harness to make it reach.

Incorrect. You need a actually extension kit that is designed for that. Just cutting and splicing the wires can throw off resistance.

Is there enough length in the harness for a 2200 to reach?

Not sure, never owned one. My friend has one with a header, it cam with the extension kit and he has no issues. I know on the LD9 you will have issues.

if you cut the harness open. you will have just enough wire. it's tight but it will reach.
Thanks, Daniel. Just wanted some good confirmation on the length of wire in the harness. Will try that first thing today.
Well i dunno what you guys are talking about i just took and cut the o2 sensor wire on my 2200 and soldered and shrink tubed it and no problems....phil
have the air/fuel measured philly...beacause even tho you may not feel it...they are right. you can damage your motor doing this.

Hmm wierd..my a/f gauge reads in the right range..but maybe thats why my gas milage has gone down..where do we get this o2 wire extender?? and whats the deiifernce or that over just extending the o2 wire?? phil

No one said you will mess your motor up, just can have issues. Usually during warm up, or in correct readings from the O2 sensor.
Also with our having a widband sensor you will never know if it is reading correctly or not.

Thanks for the input guys. I'll be trying a few things in the next couple days and let you know.
what kind of extension kit i can look for??? any brand in specific??
or name of kit or something
i try looking but didnt find.
When i put my header on, i "unwrapped" the loom, sorted out the O2 wires and had enough to reach with just enough slack that they were not tight. Patience and getting in there was the hard part. Cutting & splicing O2 wires is not a good idea, the O2 works on very very small voltage transients, or "waves" up/dn very rapidly. The car may run ok, and not set any codes but will run a little rich thus decreasing fuel milage and if you run hard - performance. The simulators work on the rear only, front sensor is where the ECM takes it's readings for rich/lean in Closed Loop Mode. Open Loop Mode is for startup, and wide open throttle only in a stock ECM.
