86 runner, 22re, i have looked everywhere for this thing and cant find it. haynes said it should be right by my coil but i only have 1 plug not connected to anything and its like a 2 pin connector

 

The Diagnostic port for the 85-86 is on the Drivers side inner fender and is nothing the same as the 87 and up. Here is T1 and E1 jumped. The codes and engine flashes are the same as the rest of the trucks on the dash.

 

Oh! It must be one of the plugs that are plugged into rubber boots on the side above the wheel well

Surprised you still have your rubber boots on the fenderwell , but that is where it should be.

 

Yeah the original owner who had it up till 2011 kept the truck in awesome shape.

 

Have a check engine light on Beach Yota?
