ok here we go this is a multi parter
1 what wires would need to be changed out if your going from DX wiring harness and putting in a Si computer and engine
2 where do those wires go ar at least what are they called and what color they are on DX harness
3 i have a code for my check engine light its code 21 i believe thats a vtec wire which one is it and where does it do name color pin n e thing helps

Can't perfectly explain your situation, I don't want to give false info. Might be better to try hybrid fourm. Use this link to get your info, can't find my cel code url, sorry. Good luck.

Code 21 = solenoid check. Need to wire from the the spool valve to A4 at the ecu.
Code 22 = presure check. Need to wire fron the little Aqua green sensor to D6 at the ecu.
Then you need a ground

i will be doing similar..... d16z6 head and p28 on 95 dx. rather than just throwing the wires, im plannig on an ex/si harness that has the vtec wires already installed... EGs have 3 plugs on the shock tower pass side.... from there to the ecu, are the vtec wire, and vtec pressure wire already thrown or will i have to hardwire it from there to the ecu???? thanks.....

sorry for threadjacking!

No only the 92' civics come wired from the ecu to passenger side shock tower. Since you have a spare harness take the wires out with the pins and wire from the strut tower to the ecu. Its real easy just get a eye glass repiar kit, use the little screw driver to take the pins out of the connectors. Them it will be plug and play using the Ex/Si engine harness. If your doing a mini me swap its going to take a little more than wiring. Go here if thats the case http://pub143.ezboard.com/bhondadseries


Sorry if this doesn't make much sense but I'm falling asleap. If you have any quesions just e-mail or pm me and I'll get back to you tomorrow.

how is there more than wiring? thats exactly what im doing... i thought it was just vtec solenoid wire (green-A4) and the vtec pressure wire (????-D6)... what else is involved? according to what i've read its just slap the head on and do the wiring... thats all....

Go here it will explain everything step by step.
