Get it if it's got the correct MB plug, that's a bargain worth trying even if it doesn't work out. If it doesn't have the correct plug I'd just get the Bosch 19353, solder it, and declare victory.

thread digging here,

the '94 M104 uses the newer fuel injection setup and not CIS-E so I cannot use the $35 mustang sensor, correct?

These types of threads are amusing to me. A new correct Bosch sensor can be had for $63 shipped to your door. It's a part that's only replaced every 60k miles. Your time should be more valuable than the few bucks you're going to save by splicing and/or soldering wires together. I mean, how much time has already been spent just trying to find which cheap replacement works?

One person spends their time -- many benefit and save money. I don't see the problem here?

Just for confirmation, I spliced in the sensor and it works.
part# 13942. Exactly the same sensor.

Don check how many wires. I believe yours probably has 4 wires. There may be a comparable 4 wire Bosch that will work too, but I haven't looked into it.

I just had a new original Bosch 13146 sensor delivered to my door for $63 total. I don't need it now, but it's nice to have. And at that price there isn't much to be saved by taking the time to splice anything. The savings, if any, would be negligible once time is factored in.

well, show me the $63 sensor that isn't some reboxed off brand thing.

I don't know if it's fair to post it hereon, so I sent you a PM.

Bosch makes lots of different direct-fit and universal (splice-in) sensors for lots of different makes.

If you use their vehicle parts finder, you'll find that the one you discussed here and used in the Ford is NOT correct for the MB. While it may splice in and seem to work fine, it won't be doing what MB designed and what Bosch built to meet that design. Your emissions may be off, your fuel economy may suffer, the performance may not be correct, you may reduce cat life, or some combination of all four.

The correct one for the 88 300TE is a 13925 (direct fit).
The universal one for the same car is a 15735.

Hold on though,

All the Oxygen sensor is doing is giving a voltage between 0 and 1 volt. If it is doing this then nothing else matters - this is all the ECU cares about.

And if the Ford sensor is the same "type" of sensor and gives this output then if shouldn't effect anything so far as the ECU is concerned.
