I recently purchased a 99 si shell that I'm rebuilding. There is a orange plug under the back seat on the drivers side that is not connected to anything. On the passenger side in the same spot it looks like a plug was in the same spot as the driver side but nothing is there. I put a picture below. What do these go to?? Thank you!!

 

To the foglights you don't have.

 

It's related to ABS brakes (ABS sensor, I think).

 

Thank you for the reply!! I just did a google search and it is the abs sensor

 

Okies!

 

Oem fog light wire.

 

Under the rear seat??!

Not.

Orange plug on US-spec OBD1+ car is always ABS related. Always. No exception.

 

Reading owns me. Did not read about the back seat. Just looked at the picture.

Looks like the pix was of the motor bay, but the ac dryer.
My bad ,

 

orange connectors are always for ABS, which a usdm si never came with.

 

Can you just run a 4040 valve and remove all abs crap?

 

I looove how the solution to all braking things is a 4040 valve.

the USDM 99 SI never came equipped with ABS, the Canadian ones did on the other hand.
It's easier during the manufacturing process to run it and not screw with the harness, not to mention cheaper.
