You can use the same concept as the OBD1 install. There is a dead end plug on OBD2 cars as well. You can use that to wire in the resistor box.

Where is this dead end plug? And what colors do i use, do you have a diagram? https://honda-tech.com/forums/images...es/emdgust.gif

It is by the master cylinder. All the wires are yellow and black. You use a multimeter and check continuity between the plug and your injectors.

There are like 5-6 wires in that dead end plug and 4 of them go to your injectors. You just have to find out which ones. You put one probe on the injector plug and one in the dead end plug and find which ones match up.

This is the easyist way to do it go to a local junk yard and pick up the connectors for an Obd 1 honda injectors and just cut your plugs and hook up the ones from the OBD1 and that is it your good to go. I have done it plenty of times and it has worked for me.

^^^ noooooooo that will not work correctly he needs a resistor box or inline resistors to run P&H injectors.

You would think that a 99 si would have a resistor box all ready.

I'm pretty sure that they use saturated injectors, not a resistor box.

Yea, they are saturated, not peak and hold. The last time i checked atleast.
