I have a 93 camaro. I did a lot of wire tucking under the hood and tiding up under the dash. I deleted hvac, airbags, etc. When I went to put things back together i noticed i cut a yellow/blk wire under the dash. From previous errors with my gauge cluster not working i know this yellow/blk wire needs to be connected to a ground. But when i was de pinning wires from things i was deleting (airbags etc) that i didnt need anymore i noticed i cut this wire. my question is, does anyone know off the top of their head where this ground wire should go to? its very small wire, maybe 16 ga.

Thanks
