Hello,

I bought this car already modified from someone who bought it modified. He doesn't know much about the car and so I am in the process of going through it to see what needs to be fixed when I noticed the gray and blue connector was unplugged. I was wondering if they need to be connected. Can anyone tell me what they are for?

It is a 93 single turbo conversion with an FC commander, HKS ignition, and Greddy boost controller.

Let me know if you need anything else.

Thanks!

I don't know which wiring harness it comes from. What will help me answer your question?

looks like O2 sensor wire(plug), check the down pipe and follow the wire.

I looked briefly but the o2 wire goes into a wiring harness so I will have to borrow a multimeter to see if there are connected. I will let you know.

Thx!

For the blue plug, your best bet is to take off the upper intake manifold and check if theres anything unpluged.

They are for the air pump.

Believe that's the EGR plug. If you have the stock ECU it should be sending a CEL that you can verify
