I got a JDM ZC SOHC VTEC with OBD-1 engine and prior to shipping to the U.S. they cut the distributor wires for for one of the plugs (the blue and black with yellow stripe). Question is can I replace this harness plug without having to buy an entire new distributor. Does anyone sell just the harness plug that I can splice to the cut existing wires or replace all the wiring altogether on the distributor?

 

Well you have both of the plugs, so I'd say, back the pins out of the connector, and find two terminals that have a longer length, and then solder them or crimp them. Backing the pins out is not hard, if you have spare plugs practice on those first. Use a sewing needle if you don't have a pin tool.

Step one: Remove the plastic retainer from the inside of the plug, it clips in.
Step two: Clean the pins with brake cleaner.
Step three: Wiggle them back and forth, and push the wire from the backside, towards the front of the plug.
Step four: At the same time as step three, use your needle and push the retaining tab upwards, and then pull the wire straight out.
Step five: Reinstall the wire grommet on the new terminals, and compare the replacements, they need to match.
Step six: Simply push the new terminals into the plug. A click will be heard. Then pull backwards with slight pressure. If they hold in place, re-seat the grommet, and solder/splice.
