Can someone help me out and post a pic of the resistor placement in the EGR plug. I'm showing Code 71 and i think doing this will trick the ecu. I've search but i can't find a pic.

No pictures, but here's my recent explanation of the process:

Is this the EGR harness i need to disconnect and add the resistor to?

That looks different than my setup. I'm guessing you have a SC300?

Wherever your EGR temperature probe is into the intake manifold, that's the plug you want to add the resistor to.

OBDII might need additional attention to tricking the valve position sensor in addition to the temperature sensor...

Yeah, I have an SC300(1995 OBD 1). The plug in the pic connects to the EGR so I'm guessing its the right one.

So, all i do is take one of these resistors, unplug the EGR cable and stick the resistor inside the plug? Also, i leave it unplugged and probably use some electrical tape to keep the resostor In place.

I would guess again if I were you.

Ok, guessing again. What I'm i doing wrong?

There are two EGR related plugs. The one you highlighted appears to be for the valve. You need to add the resistor to the one for the probe.

Okay gotcha, so i need to add a total of two resistors? One the probe and one for the valve?

t2d2

Just one for the probe. I think only OBDII needs anything done with the other plug.

Here's another pic. This is the only probe/sensor wire coming from the EGR pipe. So i cut this or unplug and add the resistor to it? Correct me if I'm wrong and direct me to correct wire/harness/probe thingy.

Ok, I think I see where we're confused. I've read references to something connected to the EGR pipe, but that's not the case on the SC400 so I'd never seen an example of it. The SC300 must have the probe there instead of on the intake manifold like I'm used to. (Aside, I hate the confusion that results from people not specifying which model they're referring to.) So, it seems likely that you've got the correct one there and want to put the resistor on the harness side of that connector.
