Ive been trying to find an O2 sensor to replace my one for pre-cat for my 1996 dodge ram 2500 5.9gas 4x4, ive tried the boesh 13100 that didnt fit, i also tried NTK 23151, none of the direct connect ones fit my sensor, any help appreciated

 

How long is the wire off your sensor?

Nice looking truck you have there.

 

why doesn't it fit?

wire length ?
or plug shape, round vs square ?

if you still have your original O2, cut the sensor off the end, save the plug, and splice it into your new O2. I had to do that. match wire colors. 2 whites, gray, black. whites are heaters, both identical, so it doesn't matter which white goes to which.

 

it wouldnt fit, theyre both circle, but the old one is longer and skinnier fitting, the wire is long enough, and idk why i didnt think of splicing the old haha thanks for that point out haha thanks man, one more thing, does any one know the wire colors and what they go to for the connect that runs from the truck to the connector

 

also im diggin the grill, was it hard to do

 

i don't know the color pattern, but if you position the wires or plug where nothing will touch or short out and turn on the ignition - then probe them, the 2 with 12 volt signal go to the heaters. one is a ground, and the other is the input signal to the pcm. i don't remember which is ground, gray or black.

 

and the 2-12volts dont matter which white wire they go to?
thanks for the help

 

I'll ask it again....How long is the wire off your O2 sensor?

 

It is 13inches, sorry for the delay

 

nope. doesn't matter.
