I have a 93 sc300, normal 2jzge. The car had horrible wiring issues so I decided to find a new harness. After a long search I couldn't find a 93 harness but I found a deal on a 95. I then cut and soldered plugs that I needed from the 93 harness to the new 95 to make everything compatable. However I did not change the plugs for the o2 sensors. The car is having low idle/dying right after it turns on until the car warms up then it runs fine with the exception of a low idle. I don't know what else to do so I'm only guessing it has something to do with it not having any o2 sensors working. This is a list of what I've done up to this point.
Air filter
MAF
TPS
IACV
Fuel Filter
Fuel Pump
Wire harness
Coolant temp sensor
Rebuilt ECU
Spark Plugs and Wires

So basically I have a 93 motor with 95 o2 harness plugs and my question today is will 95 o2 sensors fit in my 93 motor?

Also I forgot to add that the car starts right up if i give it gas before i crank it over.
