were do these go??

I've looked and looked but i need a little help now, thanks in advance guys.

#1- Located around the coil on the passenger side of the car.
#2- Located on the passenger side of the car near the battery tray, has a ground connected to it which connects beside the battery.
#3- Located on the opposite side of #1 but more between the valve cover and the firewall. EDIT: if i remember correctly the wide colors are pink with a black stripe/ and black.

Re: were do these go??

#1 - If those wires are tan and black, that's likely the extension connector for the IAT sensor under the upper plenum.
#2 - If the purple/black wire goes to ground, it goes to ground, no arguing about that.
#3 - Pink/black is operated by the ignition switch, black is ground. You'll see what it goes to once the harness is all in place and there's a disconnected device. If the black wire is just a dirty grey wire, it's the EGR connector, but doublecheck the wire color first.
#4 - I myself have no clue, hopefully somebody will chime in.

Hope this helps.
Lou

Re: were do these go??

i just checked it and it is a connector that goes between the main ecm harness and the harness that comes out of the firewall on the drivers side below the esc and the fuel pump relay. the colors coming off the firewall harness are the same colors as the connector. funny you should metion replacing the harness i just did that no to long ago, so i kind of know what mess you are in lol.
