O2 harness ?

[junkyardwarrior]

Doing a '93 Mustang 2.3L to a 5.0 swap. I have the entire harness from a 93 GT auto car...however, my car is currently a T5 with the 2.3 (still driving)

Now-am I assuming correctly that I need a T5 O2 harness even though the harness came from an auto car?

Yes, or you can repin the autos o2 harness.

Three things you want to match the transmission ideally:

Eec
O2 harness
Transmission harness (in-car)

There are ways around, but the easiest route is to hav everything match

Thanks.

I don't yet have an EEC or an O2 harness. All I have is an engine, engine harness and EEC harness from an auto car.
