Thread: resistor install?

Ive searched both forums and couldnt come up with much. I just need to know the best place to install resistors for injectors? Ive heard to install near the ecu? and also near the actual injector? Which wire should i break to install these? Ive never done this before so any help would be appreciated. Thanks

How do you wire 444cc injectors? - SR20 Forum

thank me later

Thanks that helps a little. It looks like that write up was done when you wire closer to the injector. JWT says to wite closer to the ecu. That clears up the question about which wire to use, i was getting mixed info about that.

ground wire and it doesnt matter, did it close to the injectors on mine (easier for me) and thats where a lot of honda guys do theirs.

After looking at the car it does seem MUCH easier to do it near the injector. Well if the honda guys do it then im def not Im running out now to buy a new solder gun and some shrink tube. Thanks again for the link.

no problem sir

The stock pulsar resistor box is wired on the power side of the injector. That's how i did mine and every car i put low impedence injectors into. Works fine with no issues. In the harness one power wire splits to four and goes to each injector. Most four cylinder resistor boxes have five wires, one in and four out to each injector. Normally you find that junction close to the injectors. That's just how i do it but everyone has there own way of doing things.

pretty sure it doesnt matter what wire they are spliced into

Does anyone know the symptoms of having the resistors wired wrong? I got the car started but it idles like crap and had a hard time revving past 3k.

Its in safe mode. Check MAF. And make sure none of your injector wires are exposed and touching
