Ok so I'm in the middle of a tear down on my 90 model vert and when I get to the ECU I notice this weird little pig tail coming off if it. It's been completely wrapped in heat shrink (very well I might add) and its just piggy backed onto the wiring harness. The main capacitor has been knocked off the little board, but hasn't seemed to effect the cars running ability. Can anyone help me out with this one or at least point me in a direction

It's something homemade, that much is obvious. My guess would be one of those resistor chips that are sold on ebay, but I really have no idea.

 

Yes, it looks like one of those bullshit 50 extra hp modifications that essentially tell the computer the intake temp is lower so it supplies even more fuel to our rich pig. running NA FC's. (sorry for the run-on sentence).

If you don't have the FSM (and really want to know for sure), see links in my sig. and in the wiring section locate the ECU pin-outs and see where that is going in.

 

but where does that black wire go to?

Could it be a part of some AFC system that has been ripped out?

 

The first pic shows that black wire going nowhere. I would assume it was a ground.

 

Looks like CIA technology. Is there something you'd like to tell us? LOL!

It's hard to tell from the pics, but which PIN is that going into on the ECU?

 

Thanks for the quick responses! The black wire was a ground but I screwed that up scrapping out the factory sound deading material. I'll check to see what pins it connected to when I get back to town. I thought it might have been some kind of homemade fix for the flooding problem, but I wasn't sure. Thanks for the help
