OK guys heres what happened i planned to go turbo on my h22a4 in my 96 honda accord, so i got the turbo kit installed (t3t4) and like any turbo setup i bought some low impedance DMS injectors 450cc (blue tops) with the resistor box. I did my research through the honda forums how to install that resistor box and it didn't seem difficult until now.
All forums with dsm injectors and based on civics mine is accord, so i used common sense.
civics forums said to connect the 4 black wires from the resistor box to the yellow and black stripe wires that are on the left side of the engine bay, which are the ones comming from the injectors to the ecu, is this right??????

So I went ahead and did the same thing four wires from the ecu to the injectors- This is where i put the resistor box.

Out of the 5 wires from the resistor box four black cables each one goes connected to the injector clip and the red cable from the resistor box to the four injector wires coming from the ecu which are Pins: A1, A2, A3, A4 red, blue, brown, and yellow (is this right??????) The way i did it was testing continuity from the injectors connector clip to the connector harness right by the left side of the engine bay. once i got the four wires i needed i started cutting wires to put the resistor box.

This setup worked just fine. The car did turn on and everything started running fine. This car is my daily i drive to work like 20 min. But after a 30 to 45min drive the battery light comes on and off. and it comes on and off every time i hit the gas pedal or when it idles. my ecu (apexi power fc) commander, says that the battery voltage is 15.9 which is pretty high when hitting the gas pedal but if i let it go it goes down to 12.5 volts. and the car feel like its carrying 2 tons of weight because it bogs down and doen't like it when i hit the gas pedal, if i turn it off it does not turn on back.

I dont think it is my generator or the battery because this problem started right after installing the injectors and the resistor box.
I dont know what else to do, what is it wrong?????

Since it the battery light came on i decided to connect to the other wire on the injectors. the red and black stripe wire each on all 4 injectors. Those four wires were connected together to a yellow and black stripe wire, which i dont know were it goes to? My guess is to ground on the ecu.

I tried connecting the resistor box with each black wire to the red and black stripe and the red cable from the resistor box to the yellow and black stripe cable and this setup didn't work on my car it didn't turn on at all. I tried this setup because i saw it on a 92 accord, with the resistor box.

So i left it just like it was before the four red and black stripe wires to the yellow and black stripe wire. and my resistor box red wire connected to the yellow, brown, blue and red wire coming from the ecu, and the resistor box black wires to the injectors. But i still have this problems with the high voltage and dont want to damage or burn anything, also the car is not tunned yet all i am missing is to install the fuel pump. I dont want to take the car to my tunner with this problems.

Yall help will be very much appreciated, thanks in advance!!!

The red wire on the resistor box is the (+) wire and it ties into the main relay yel/blk wire coming from the fuse box. The 4 black wires off the resistor (+) go to the red/blk wires on the injectors.
The coloured wires from the injector go to the ECU as follows

OBD2 ECU wire code
Inj #1 = BRN wire - goes to PIN A1
Inj #2 = RED wire - goes to Pin A2
Inj #3 = BLU wire - goes to Pin A3
Inj #4 = YEL wire - goes to Pin A5

Thats how I did it on my 2nd attemp to get rid off the battery light coming on and off.

i connceted back the colored wires of the injectors directly to the cables going to the ecu.
Then the + red wire from the resistor box to the yel/blk wire from the fuse box, and black wires from the resistor box to the red/blk wires to the injectors. and the car didn't turn on.

and the red/blk wire points to and is connected to the + side on the injector clip.

i am kinda tired right now, so i didnt read through your post carefully.

but, did you remove the stock resistor box when u installed the h22a4?

because your car should have a resistor box stock.

if you wired another one inline with the stock one, then thats probably your problem.

GhostAccord

Good heads up..... I wasn't even thinking about that. The DSM injectors work with the stock injector clip wiring on our 96 Accords.....

when i bought the car it came with the h22a4 and it did not had a resistor box installed. The stock injectors are high impedance so it does not need a resistor box.


Sorry not to mention that i did modified the clips I wired the dsm ones to the injector wiring.

ah ok. well the way the honda wiring work is, the resistor box gets a 12v switched input, then the other 4 wires goes to each injector. order does not matter because its just feeding a 12v source to the injector with an inline resistor.

then the ecu supplies the ground to each specific injector which pulses them.

what you shoud've done is, check wihc one is the 12v switched power source going to the injector and replace that with the output from the resistor box. then hook the 12v switched source directly to the input of the resistor box instead.

now basiaclly waht you have is 12v into the resistor box, through a resistor in the box, and out to the injector.

the ground signal wire coming from the ecu should be left alone because it should still come directly from the ecu. regardless of sat/p&h injectors.

ok i will definetly going to double check my wiring, and try it again.

How should I test the 12v power source on the injector wiring with the key to on position or by cranking the engine.

Eddiebx

definitely dont crank the engine. check for the switched 12v by turning the key onto ON position. it shuld only see 12v when in that postion.

allright I will try with the key to the ON position.

ok i figured out what was wrong and it wasnt the injector wiring or the resistor box IT WAS THE ALTERNATOR that was starting to fail and there was not enough eletricity.
Yes the injectors red/blk wires are connected to the black wire in the resistor box and the red cable from the resistor box goes to the yelow/blk wire.

Thanks guys for yall help!!!

haha go figure. glad you got it to work though.
