Sorry, another dump plug question from me. Hopefully the last one, I swear something in my brain just shuts off any time I look at these. I have a manual but even if I found these plugs in them, they're only referred to by their pin # and not by what they actually do.

Anyone know what these two plugs are on the driver's side (93 Civic Si)? Been too long since I moved these and don't remember, or see where they're supposed to line up.

 

Looks like the O2 sensor plug and the intake air temp sensor plug.

 

The 2P connector may be for the Power Steering Pressure switch due to the wire colors.

Still trying to match the wiring colors for the other connector.

 

The 4P connector may be Connector C313 which goes to the Cruise Control Actuator.

 

Thank you both very much.

 

It appears that the wires have been spliced in the past... so I cannot tell if the wire colors in each plug are original (are they the same color on both sides of the splices), and if not, what are the colors on the chassis side of the splice ?

 

Only the two-wire connector has been spliced, the four wire was repinned, both should have factory wire colors.

The two wire is one brown/red wire, and one black.
The four wire is brown, black, brown/white, and brown/black

I don't see anywhere on my PS rack that has a switch, or spot for one, did all PS cars come with that switch? If not then it could be the intake air temp sensor like Maxcapacity said, I currently have the Rywire harness plugged into that.

I should be able to look into this more after work today as well.

 

The PSP wires are Brn/Red and Blk. An IAT's wires are Red/Yel and Grn/Wht.

 

Thank you. Isn't the PSP switch normally located inline on the power steering line?

In which case I guess I've "deleted" mine since I'm using the Chase Bays powersteering kit. As far as I'm aware the main job of that switch is to help keep idle smooth when using the power steering at low RPM like in parking lots.

 

It is attached to the pressure hose, that previous photo from Honda's manual is dark, covered up and not a close up.

 

Thank you Tech8, and others for input. In this case I'll be tucking away/removing both of those plugs. I no longer have the PSP switch, and I've also removed cruise control since I'm using an aftermarket wheel.


Thank ya'll very much.
