OK normally I wouldn't say this but.......I give up! does anybody have a diagram or any info on how the 3 pc under dash insulation puzzle fits and is it before or after the heater box

 

I almost gave up also, until I realized that one edge matches firewall at heater box area and the small pc went above the fusebox...black side down. I put mine in before everything else....pretty simple with spray contact. Hope this helps.....LMK if you need pics

that sounds easy enough but as an adult learner I definitely need pics.THANKS!!
