Ok I have an 89 HF shell, and the engine wiring harness to an 88 SI. I noticed this when I was install my engine this evening, it has been a while since I have messed with an obd0 car. My question is what are these two plugs for? and are they supposed to connected to each other, for a point of reference the picture is taken an the drivers side strut tower where the resistor box sits as you can see in the pic. Please help!!! Thanks!

 

those are supposed to plug into ur interior harness...
but i don't see it....where the h*ll are they?....!!!!!

 

u should be using the hf harness btw...

 

use the HF, the only difference is usually the plug for EGR

 

I don't have the hf harness, that's the problem
