Get your mind out of the gutter.

I pulled my right front fender off today & found this square hole which leads to the kick panel area. It is shiny around the edges like something used to reside there. I ripped the interior out a long time ago so I have no clue what was there.

 

maybe a vent? im not sure

 

That's where the ECM harness used to run through.

 

ECM harness use to be there.

 

Yup, thats the ECM harness hole.....

 

yup thats where my ecm pluggen in

 

Uh, It could be the hole for the engine harness, but I am not too sure. Do you have a shop manual around to verify?

 

ECM- o.k. that makes sense. That hole is the reason my "check engine soon light" has been on for years.

I'll just weld in a patch to seal it. Thanks everyone.

EDIT: oh, and Zepher, I do have a Chilton's manual, but there was nothing in the index under "mystery hole."

 

I think it mentions ECM Bulkhead connector in there somewhere.
It might have been in the GM service manual though.
With the T/A fenders, it is easy to get to and weld shut with the fender still on the car,

 

Yeah, I should probably get a service manual because the Chilton's isn't very comprehensive. But the car is such a mutt now that I wouldn't know what year manual to buy! (83 body, 91 nose & tail, 89 interior, early 70's engine/trans, 86 Iroc rearend...)

 

im all cobbled up too. 88 Firebird 2.8 originally. Now a 355 carbed with 350 turbo, 89 Formula BW rearend. 89 bront bumper.

 

If we are talking about different year parts, I have the following:
84 Trans Am Hood
87 Formula Hatch
91 Camaro Rocker Panels
96 Camaro Steering Wheel
95 Formula Rear End
95 Caprice LT1
94 Corvette Heads
96 Trans Am Seats
86 Iroc Wonderbar
85 Trans Am Seatbelts
97 Trans Am Console
95 Camaro 4L60E

 

yea, i think its safe to say your car is cobbled up lol

 

zepher, i don't know much about trans am's, but why is there an enormous hole in the fender?

 

There is a fender vent insert that goes there.

 

is that stock, or custom? how hard would it be to put in a camaro?

 

It is stock on the 82-90 Trans Am's.
Shouldn't be too hard to put onto a Camaro.

 

There is a slight lip there, but someone who's a decent metalworker could make them fit in any fender. I'll be trying that myself on a stock Firebird fender, since they're a lot easier to find (and cheaper) around here.

 

yep...you found it...when ever you have a problem with your camaro and it's difficult to find, check in that hole cause that's where the gremlins hide...

kidding, ECM...
