This is about a 3 foot long harness. Maybe power top and cruise? Rear defrost and cruise? AC and cruise or top? One end is is the first picture. One of those plugs has 3 very thick gauge wires. In the middle are these connectors... One a clear, 3 way type.... Far end is just 2 black plastic connectors with regular gauge wires.... I looked at the 4 speed harnesses I have and none of them have this harness.
The one looks like it is the fiber optic for cruise control. The heavy duty one is probably for power top.
