What is this connection called

In me nightmare of trying to make this thing run, I ran into this connection attached to the backside panel of glove box. (Right side)
What is it. I did not notice it when I went in to reseat the ide type cables on the ECU.
I reseated both and locked them back in. Lo and behold all my issues of the miss went away.
I drove to work and back and half way home the CL came on so hooked up scanner and actually got a code p402 which I will deal with later as it’s running and that’s all I need for the moment.

 

What year and engine is your truck?

 

95.5 2.7 4wd regular cab

 

I'll have a look at some diagrams later and see.

 

Only thing I know about it is that obviously connecting at least part of the ECU as it fixed my OBDII scanner issues and spark problem. Just would be nice to know what to call it

 

Looks like that is going to be connectors IK1 and IK2.
I can see IK2 being a problem if it wasn't plugged in all the way, just at a glance Ignition Power for the injectors, igniter, & distributor go through Pin 8 and one of the grounds for the DLC goes through Pin 6.
