I think the confusion on wire color comes from using the 88-89 knock boxes, there are a few color differences from one side of the connector to the other whereas the 87 and earlier knock boxes have no wires on the knock box side. So for an 87 and earlier you would cut the connector off the wire loom and look for the wires you need. The white and black from the distributor are VR+, - and are bundled together with a shield (braided outer metal), you may have to unwrap the harness a bit to see everything. The single white wire with shield is the knock sensor in, you don't need that. There will be a single black wire that goes to sensor ground, you don't need that. The red wire is switched 12 volts, you need that. The yellow wire/black stripe and brown wires are not needed which just leaves the blue wire/white stripe that goes to the negative terminal of the coil. Also note that if you unwrap the harness a bit that blue wire/white stripe is "t"'d with a white wire, you need to leave that there as the white wire supplies rpm input to the ECU. For an 88-89 the wire colors coming to the knock box plug that you need are the same, just be aware that if you set up the 4 pin inside the box like the pictures above you need to folllow the wires through the plug to see if they change color.
I ask for your expertise because you were one that was sure it worked. The convoluted information about JA starion distributors working and our US versions not working only added to my confusion. Im scared ****less to fry something trying this on my own.
