Cheap 4 wire o2 retrofit

[SamE30e]

This sensor is a 0-1v reading, does anyone know what the M50 requires?

I like pictures with write ups.

m5o is 0-1v

your problem is not your o2 but in the 13-13 connection.

i have a 1992 m50 in my car (non vanos) i believe she was built in o6 of 91 or so. but i cant even find the port for the o2 sensor! did that year not have one? sorry if this is a stupid question. anybody know what id tap into in the engine harness if i had to install one?

[xLegendOZWest]

I did the 3 wire sensor that is listed in this thread on page one and it appears to have worked for me! thanks for saving me a lot of cash guys.

It worked, I passed emissions.

Elephant...thanks for the skinny on the info your site provides...matched my car up to the Bosch 15718...Works great...was only $40 Bucks!!!

i can post pics if anyone wants, but basically cut the wires, soldered the old BMW plug onto the new sensor, heat shrink on all 4 wires and slid the new heat shield back over the wires...

Installed and GTG!!!

Mid 90's Dodge intrepid sensor also works and I found to be the cheapest.

Do you have the part number or the year for the Intrepid?



Does anyone have the complete write-up? The pics seem to be missing.

I just bought one for a 2002 Ford Mustang 4.6 (Bosch #15716) today. Will probably attempt to install sometime this weekend. Kind of wish I would have noticed this thread before I went shopping. Didn't realize all 4-wire O2 sensors are not the same. Hopefully this one will work.

When I get to work I can go through some random boxes and find the cheapest bosch 4 wire. We have about 100 of them.

Im going to use a bosch 15704 should work 0-1v.

Worked Great IDK what they cost though so it might not be cheaper.

I'm looking to do the 4 wire job on my car, but there aren't any images posted here any more.

Can anyone tell me how I should connect a 4 wire sensor to my 3 wire harness?
