hi im wiring up my resistor box directly to my injectors.


this is the picture im using as reference. can somebody tell me how i would connect the red wire to the 4 ecu wires? do i just T them?

You use the 12v junction plug over at the driver side strut tower. There are 7 yellow/blacks there, with 4 of them going to the injectors. Wire the injector (4 out wires from the resistor) to each of the injectors. The remaining three should just be all connected together and connected to the resistors red (power in) wire.

 

i have an obd2 motor. my dead end plug is underneath my manifold, i cant seem to get the cap off of the dead end plug.

one other thing. I have a resistor box, but i odnt have the other end of the plug for it. When i received it, they removed the connector and just gave me the resistor box.

 

that is how i have it wired.

 

are you suppose to connect the non common color from the injector clips and the ecu together?

 

Yes, yellow, blue, red, brown go to their corresponding locations at the ecu. Yes, OBD2 you use the junction underneath...I've done it many times on various swaps in the past. As far as the cap goes, you don't need to get it off to wire the resistor in...it can stay.

So, like I said, identify which of the four in the junction go to the injectors, then wire them to the four black wires on the resistor, combine the other three/four remaining and attach them to the red wire going into the resistor....cake dude...just get it done.

 

yeah i wired them up, but when my motor starts, i cant pass 3000 rpms. i'm pretty sure its my injectors that are not letting me go pass 3000

 

That's highly unlikely to be it. Wiring those is straight forward and almost too simple to f*ck up. Get someone who knows what their doing to check your sh*t.

Is the thing running normally then hitting a brick wall, or is it a sluggish pig all around? You have an engine light? You got other problems I'm willin to bet.

the motor ran well with the turbo off, the only cel i had was the secondary o2 sensor. When i start up the car with the chipped ecu, the car idles pretty smooth. After I hit the throttle, it will rise to about 2600rpms and then be VERY sluggish and not be able to move pass 2600. I am pretty sure i wired it correct, i check like 6 times.

 

Dude...I looked in your other thread and there your saying you have a solid CEL...your injectors aren't it like I said. Solid CEL in a chipped ecu either means the installed components are bad/installed wrong or it was a bad chip burn. When the ecu can't reference that chip is goes into limp.

 

ok cool, how do i check if i have a bad ecu?

 

if a ecu has a solid light it could also be a blown diode or transister it just happened to me
