Look up the ECU pinout for your car and solder them in the wires corresponding to the injectors you put them (if you put them only in secondaries only in the wires for the secondaries, if you go with 4x720 1 resistor for each injectors). It's better to solder them in at the ECU as opposed to in the engine bay to keep them away from heat/vibration etc.

You dont have to open up the ECU at all. It's alot easier than you think. Just cut the wires for each secondary injector from the ECU harness and then solder in a resistor for each.

Damn, I just received my injectors back from WitchHunter. I've got to say, THEY ARE AWESOME!

I received brand new upper and lower grommets and o-rings along with the very well packaged, cleaned and flow-tested injectors!

Highly recommend sending your injectors to WitchHunter!

We are in the Seattle area. Turn times are 1-2 days but it's getting close to the busy season. Already doing 12+ hours a day to keep the customers happy.

they are listed as 690's in reference to their original intended use in the GSL SE 13B engine which has a lower fuel pressure rating, up the pressure to what the S4 and S5 use and they easily flow 720cc's.

Denso 1995500-0830

Radio shack resistors 10ohm/10watt package of 2 #271-132

Dont be so lazy and look up the pins yourself. I had to walk downstairs to get these part numbers for you guys lol.

actually the workers will know right where it is. I had one that looked like he should have worked at McDonalds however some sort of basic skill they taught him came back to him and he showed me right where the resistors where. THen all you have to do is look for the backages that say 10watt 10ohm
