I have a 95 lt1 and I'd like to put my 685 box in tonight?

 

I didn't want to buy the harness but I never could find a good answer on how to wire the box without the harness. I ended up buying the harness and I am glad I did. It made the install very simple and clean. Plus, if the spark box ever dies (which seems to happen a lot to aftermarket boxes) all I have to do is unplug the harnes and plug the coil in like stock and I won't get stuck. I would hate to be stuck on the side of the road splicing wires back together wishing I had bought a ~$20.00 harness. Sorry I can't help you get it installed tonight.
