Hi- I guess I need to lengthen my 02 sensors...
Do I do it to the harness?? Whats involved? Thanks!

 

I used some white plastic connectors with threaded "collars" on the ends that I found at my local auto0 parts store. I added about a foot to each O2 wire, wrapped them up with tape and put some split plastic corrugated wire protectors on them. No problems.

 

Don't do it would be my suggestion. I have heard lengthing them by wire splicing can effect the sensors. When i had my motor out i bought harnesses and did it the right way.

 

They wont reach with the long tubes in.

 

I got some heat shrink and solder in a section of wire I only had to do one side on mine...Then wraped in heat rap.

 

If you lengthen them by yourself, remember a couple things:

Lengthen from the engine harness side, not the O2 side.
SOLDER, no crimping
Save the headache and spend 50 bucks for premade harnesses.

You have probably spent a bunch on your car, why skimp now? (This logic can get you in trouble, but 50 bucks for a surefire/no electrical nightmare scenario is money wellspent IMO)

Why spend 5 grand on a pimp Bogner amp, a McCarty PRS and then use an extra cheap $0.99 chord? That analogy should hit home!

Wow- that analogy hit REAL HARD. lol

I didnt really want to cut and paste. Where can I get this harness??? And how ya been buddy?

 

F-body cetral sells it. Heres a link:

You can spend the 50 bucks, or you can extend them yourself.
I have Bosch O2s that I crimped some wire into and they work fine.
I don,t reccomend splicing your harness hard to replace that if it gets screwed up.
Alot of people complain about the Bosch O2s and many on here say not to extend the O2 but to extend the harness side and they have all kinds of nightmare stories.

Do what you think is best but I have crimped wire into the O2 sensor side of Bosch O2s and have no problems. I have a scanner and can watch what the O2s are doing and they are fine.

 

Hey there!

I bought them from Thunder Racing - get the 24" length.

Drop me an IM next time you're on bro!

there is absolutly no reason they should go bad by simply extending them yourself unless you do a bad job or solder the wrong wires, the current wil still flow just as well as the store bught units. Some say its a pain, I found it to be very easy, tok me maybe a half hour, you just have to work inside the engine bay, that is if you extend them form the harness side, which is much easier to swap to new ones. Just make sure the solder flows to the inside of the wire, leavng a completely fused unit. then cover them up with shrinkwrap and your done. I put some of the plastic covering that ges over wire bundles to make it nice and clean. I also used a scanner on these and the combination of home cut wires and Bosch O2s are working great I paid 2.50 for the wire length to use, so its real cheap.

 

Well, I decided to simply extend the one at the harness- and all is well.

Shrink wrapped, and taped for protection.

Thanks!!
