The 86 distributer you are trying to use was made to work with a computer, you need to find a distributer out of an 75 to 82 chevy v-8 with vaccume advance.

If you absolutly have to use that distributor you can connect the black and brown wire together, This will bypass the EST(Electronic Spark Timing) circuit and allow you to time it as usual.

Or you can replace the ignition module with a standard 4 pin and just remove the old 4 wire harness from the housing (put silicon in its place though)
