I have a 90 civic hatch and I had the relays under the dash pulled so I could test them and low and behold my dog snuck them out of my tool bucket and chewed one of them. The problem is I dont know what it is to buy a new one! Its a larger six prong black ventilated box that came from under my driver side dash.

i think thats your dash-lights dimmer.

 

I dont think so it doesn't have a dimmer switch or anything on, just the six prongs for the connector. Screenshot by Lightshot Here's another view. I've been looking online for almost two hours now and still no dice..

 

This should be able to help you:

Yeah thanks but the dog is staying. Does anyone know what this is though? I thought this would be the best place to find out

 

I owe you an apology, upon getting my car running again I realize that my dash lights no longer work and that's the one thing that's not in working order.
