d15b codes 21 and 22

[tunerfreak87]

im runnin a p28 with my d15b and i havent wired up my vtec yet. can someone give me a link or give me a walkthrough of how to fix these two codes and get my Vtec engaging? thanks a lot.

Like you need to know what pin it goes into the ecu?

[tunerfreak87]

i need to know the whole process of wiring up the vtec in my dx and i saw you on another thread like this so i know you can help me :) to get rid of the 21/22 codes and get Vtec werking.

and here is a link that may help to find out the pin.

and did you do the cnversion from dx, to si?

[tunerfreak87]

kk ill check tht link, i have the si harness and the p28 and thats it. all i did was drop the motor in and plug in the harness and called it a day.

[dustin_crxsi]

the easiest thing to do is go to rywire.com and but the conversion harness from DX to SI, then the OBD0 to 0BD1

[tunerfreak87]

i have OBD1 already, its a 94 DX. i thought you just had to run the two wires to the ecu and put them in the pins and then a ground or something?

[dustin_crxsi]

Oh, well let me look around for ya

[tunerfreak87]

ok cool, can u post that tonite? and where can i get those little connectors that will let me plug the vtec wires into the sub harness and ecu plugs?

that may help

from a donor harness, or make your own

[tunerfreak87]

so i just get some wire, run the two vtec wires from the sub harness to the ecu plugs? do i just stick the wires in the plug or how does that werk?

btw thanks for those two links they solved like 80% of my problem.

[dustin_crxsi]

you can, but you can also make a pin. If you have a harness laying around, Or some connectors, you can attach the wire's to a metal Pin, and make it look decent, and maybe hold better.

But you can just push the wire into the hole where it needs to go.

[tunerfreak87]

oh and is there a ground from the d15b Vtec solenoid?

ok i have an extra si harness so do i just take out a couple pins from one of the plugs?

[dustin_crxsi]

Yea, their is a ground. you can connect it to the body, or engine.

You can take the pins out. If I had some things laying around Id be happy to show you.

[tunerfreak87]

how do i put the wire into the sub-harness part rather than the ecu plug because im lookin at my other harness here and the shock tower plug has like little rubber things holding em in not little metal things like the ecu plugs?

[dustin_crxsi]

Modify it if it wont work at all, then just plug the wire into the computer.

For now

[tunerfreak87]

alright ill go with what i know now and ill try wiring tomorrow! if you find anything elses tonight post it up and ill check on here be4 i start to wire

thanks man

No problem. Ill do a write up tomorrow about using an existing plug from a harness, to put in the ecu.

I love to wire shit up :TU:

thread solved lol

[tunerfreak87]

i have the firewall side plug from my jdm harness that had vtec wired sooooo ill i gotta do is take out the two pins from the jdm plug for the vtec and put them in the empty hols in my dx harness plug and splice a longer wire onto the pigtail thats already there and stick it into the ecu and im done! and its all oem :) and yeah slap on the ground too.

[tunerfreak87]

one problem...D6 on the ecu is a smaller pin like all the middle pins on the ecu and i cant fit in the pin because its too big. pin A6 works because its the same size as the pins from the engine harness. wtf? how do you do this?

[tunerfreak87]

ok i figured out the pin issue now i have in issue left...

how do i get the pins back into the engine harness? i got them out by just pulling but i cant seem to push them back in my harness plug on my car. pushing the pins into the ecu plug is easy cause they jsut slide in but on the engine harness i cant get em thru, what can i use thats small enuff to stick in the female end of the plug?
