To give you a idea what you really need the Si harness for. If you can find thes parts seprately you wont need to bother finding a harness. I may even have a few of them in my stash of harness’s or Hondarat on here may have them as well. All plugs will need at least 3" of wire on them to be able to splice to. Soldering is a must on the mpfi swap! I have seen/ fixed so many issues with butt connectors during this swap.
~Injector plugs with clips
You can actually eliminate the resistor box by running OBD-1 injectors and plugs. I recommend running it though if you happen to turbo it, you would have to add the box in anyways. You can always run OBD-0 injectors and the box even if you swap to OBD-1 in the future.
Resistor box with complete plug
Round Si distr. plugs (std/dx ones are square)
I’ve got the resistor box already. Let me know if you happen to have anything laying around. I got a few more things to get (dizzy, injectors, gaskets, some hoses) but I really would like to do this swap by Mid September.
