Thread: High port injector dropping resistor, eliminate for low port swap?

My Google abilities have failed me, I know this has to have been covered but I can't seem to find it. The EF & EC section of the FSM (Page 370 on the one I'm looking at) for the '91 B13 shows that there are dropping resistors inline with the fuel injectors. This is shown on the overall circuit diagram, but not on the wiring chart that shows the wiring colors. Even though the schematic shows 4 resistors inside of a rectangle with a total of 5 wires (1 in, 4 out), the box is simply labeled Dropping Resistor, as if it is a single resistor and is shown as 4 items on the schematic.

Anyway, no dropping resistor is shown on the low port schematic for either the '95 200SX or the '00 G20. I honestly can't remember which injectors I have for this low port intake manifold at this point, but I'm going to assume that this resistor isn't needed?

The injectors I have included a wiring harness w/connector, and I have a connector cut off the harness from a '00 G20 that matches, I'm planning to match up the wires to make this work.

I haven't yet unwrapped the wiring for the high port injectors, I'm assuming the resistor (or resistors?) are somewhere in that assembly?

That pretty much matches my manual, on the page that shows the wiring colors, here is my version, which doesn't indicate any resistor:




But, the page that shows the more complete schematic is the one that shows the resistor inline (lower left part of this schematic):




The manual these are from is the B13 and N14 Series manual, which includes the GA, SR, and SR20DET models, not the US specific manual that didn't include some of these other variants. I may have to dig up my paper copy of the FSM tonight...

OK, several days of puzzling over this and it finally hit me last night. I wasn't reading the diagram right. Yes, it clearly showed the resistor(s?) there, but there was also those circles with E T and T C in them, I kept thinking that was a connector designation, but I had forgotten about the diagram key in the upper right... The ET designation means Non-Turbo, the TC means Turbo. The ET clearly showed a direct connection over to the battery, only the Turbo model had this resistor in the circuit.

So... Nevermind.

Pretty sure the dropping resistors are only on the GTiR, which uses top feeds.
