I'm extending the wideband o2 sensor adapter harness so i can place it inside the car and not outside so it doesn't hit the heatshield surrounding the exhaust piping.

I have a question.. I cut the adapter and the wire is SILVER, i only have COPPER speaker wire to extend it with, will this effect the readout signal of the wideband by using copper with silver or should it be ok?

 

It will be fine

 

Buy a silver wire. The copper wire is fine but it will corrode because its not the same metal. The reading is going to be fine because there is only 3.4 difference between copper and silver. I hope this help. Make sure you solder it too.

 

Its a Bosch sensor and ive read you cant solder the original silver wire because its stainless steel wire.

 

thanks for adding the solder part...solder everything..and use heate shring tubimg with sealent if the splice is exposed to the elements

 

well you cant solder stainless steel unless you have a open flame, my iron gets hot but not hot enough to compete with open flame.

I put on radioshack #64-033 wire connectors and i was going to heat shrink tubing over the connectors.
