I have a h22 in my 98 civic, im running a p28 ecu do I need a resistor box?? and how do I wire the box to the injectors?? (I already searched) ty

 

your need for a resistor box depends on your injectors, not ecu. obd1 injectors (345 cc) need the box, the obd2's (290cc) do not. do a search for resistor box wiring, and you will find your answer.

 

I have obd 1 injectors

 

then you need the resistor box. wire it like this

you can get a resistor box from a junkyard real cheap.

 

Wire it like this,

 

the red wire goes to the clip and then to the ecu? the wire from the injectors have to go to the clip??

 

Basicly you find the clip with the black and yellow wires, find out by doing a cont. test and cut them, wire the cut part from the injectors to any of the black wires from the box and the ones from the clip bunched all into one on the red wire. and wal la

That clip makes it look like the signal wires for the injectors are going to the clip (which they are not). That clip is a distribution block for power. Heres a better pic (taken from page 1 of the write up)



Heres a helpful link as well

ok I wired the blk/yel wires from the intjectors to the wires on the box

here is the clip where the red wire from the box goes to rightright

ok so where does the seven other wires from the clip go to???

thanks for the help tryin to get this baby started h22 baby

You're gonna have to look at teh engine wiring diagram for teh H22 to make sure (or continuity test a known good H22 engine harness), but for my Integra....those IGN 12VDC+ leads from that distribution block go to:

oxygen sensor
IAB
IAT
(4) INJ's
(1) for the 12VDC+ input

it looks like your having a hard time doing this so here it is just follow these instructions and youll have no problem hooking it up. ive never been good at following pictures so heres an explanation. get a resistor box at a junkyard and dont let them charge you more than 10 bucks. youll have 4 wires on it of the same color and one more of a differnt color take the box and mount it somewhere. take the one wire differnt from all the others on the box and wire it to your hot wire on the distributor clip. the clip you use for this is the one with only two wires on it you need to wire into the bigger wire of the two. then disconnect your injector plugs to make this next part easier. look at the wires that go into them there will be two wires on each injector clip there is the same color wire going to all injector clips and the other one will alternate so listen up on the injector clip find the wire that is the same on all of the clips cut only these 4 about 4 inches from the clip then cut 4 lengths of electrical wire that are the same length. now you have 4 injector wires and 4 wires coming from the box connect one wire from the box to one injector make sure the wire goes into the injector clip not onto the wire that goes into the harness. continue connecting one from the box to one from the injector until all 4 are connected and then your done. sounds complicated reading this just print these instructions and get to work they will not fail you.

 

It only sounds complicated because they're run-on sentences.
