Finishing up a swap, I'm confused with injectors with resistor box???
I got a z6 into a 91 crx si and trying to finish up the wiring.. I have a obd0-obd1 conversion harness, z6 dizzy, p28, using the stock a6 engine harness... I'm stuck on which injectors? since using the p28 it would need z6 injectors that are obd1 right? but what happens with the stock crx resistor box? do I sauder all the injector wiring going to it together? AND yes I have searched repeatedly and I need a simple answer instead of getting the run around. Someone must know off the back of their hand.. PLease help..

I'm currently running my obdo b16 injectors with a chipped p28. If you have an SI you already have the resistor box.

if your running OBD1 injectors and everything else is OBD1 you can remove the resistor box. There are two plugs that run to that side as well, one I believe was attached to the resistor box. One of those you'll need to depin, repin with an OBD1 plug, and cap. The other one you plug right back up to your harness.
The process of deping, and capping has been covered before. Search here, and on Rywire.com they have OBD0 to OBD1 conversion instructions, the process is also listed on there.
Good luck.

I think he's aware that he has a resistor box genious . The answer is if you're using an obd0 injector then you keep the resistor box. Since you're going to use obd1 injectors which are not peak/hold, you do NOT need the resistor box. Simply disconnect the resistor box and remove it, then solder all 5 wires together (4 red, 1 yellow) Some company whom i cannot recall the name of also makes a clip that plugs into the stock resistor box clip that effectively routes all 5 wires together, which would be the better and generally cleaner choice of course. Now granted you have to spend money for this thing where as you spend nothing just soldering them together. I did this with mine, then taped it up real tight to the other harness that sits in that corner, and now its like it was never there.
