84 Dodge Ram spark control computer

I have searched pretty thoroughly and cannot locate the spark control computer on my 1984 Ram B150 van (318 V8 automatic w/ air). I'm beginning to think I have one of those rare vans without a SCC, but it's a California vehicle so pretty much has to have one. Can anyone tell me where on the vehicle I would be if I was a SCC? thanks for your help!

Hey, I have an 84 Ram B250 Van.. Look on the firewall, it should be a silver box, with a wire harness running to it that plugs in. But there is a screw that goes in the middle of the harness that holds it in tight & snug.. Look there.. If thats not it, hit me back, i got all the books, i can help ya... djkraze26@aol.com
