I ran all my nessacary wires inside the car for the Vtec Oil Pressure, Vtec solenoid valve, knock sensor, air intake bypass valve, EGR lift sensor, EGR solenoid valve, and Heated Oxygen sensor. What im confused about is since im converting my car to obd1 where do hook all these wires up? Do splice into where the engine harness connects to the jumper, or do I splice into the jumper, or directly into my P13 ecu?



The is a 99 dx coupe with an 94 H22.

i dont know if this will help with the obd2 > 1 conversion

Yeah I already have that and it just doesnt clarify what to do when converting.

 

bump it

 

What I did was this:
Since I had an extra engine harness laying around, (Read: I screwed up the first time and got a 96-98 one instead of the 99-00 one ), I pulled some pins out of the other harness plug. Then I just pushed the pins in the existing engine harness plug to the ECM, and did it that way. BUT, I have seen it done where you can hack into your adapter harness. Just make absolutely sure that's the right wire. This way is not recommended, but will work if you securely solder everything.
If you were to do it that way, I would suggest not cutting the harness, but simply stripping the shielding off the wires and wrapping the new homemade wire around that and soldering that. That way, you don't endanger the harness.
I hope this helps bro?

 

Okay if I am understanding your questions properly you would want to tap into the adapter harness side since that is where it converts to ODB I. And you can just splice into those wires either by soldering or a crimp adapter, either way will work just fine.. And then you can use the above diagram to match the right pins for all the sensors on the side of the p13..

If you have any more questions just let me know..

 

I would suggest you go over the jumper harness and see if the wires are on the jumper harness. If the wires are there then hook the wires up with ECU pin right into the original ECU plugs. If the wires arent in the jumper harness then run thr wires into the jumper harness plug that plugs up to the P13.HTH

 

Well like i told him on PM, since his motor is already vtec equipped then his harness should already be wired up. At most all you have to add is the knock sensor and your done..

 

Yeah my bad I forgot the word not when I told you my my car was not vtec equipped. So what everybody is saying, is that I should splice into the jumper harness, to hook everything up? Would that be easiest? Because where the engine harness plugs into the jumper harness, the engine harness has like 3 rows of pins. It seems that would be the best place to tap into to add everything I need to, but since its 3 row I dont know which pin is which.

 

like I said if vtec and all other wires are in the harness then simply plug in the wires where I circled in red. If you firnd that the wires are not on the jumper harness then plug them up directly to the ecu which i circled in green.

 

Thanks man, it seems that I will most likely wire everything up where the green circle is, it seems like my best bet.

 

When looking at the jumper harness referreing to the diagram posted above or the the lock which is the top and bottom? Because my problem is on my jumper harness there is no wire going to D12(EGR Lift Sensor)?

Also on the OEM side of the civic harness if I happen to tap into there where would I tap into?

There is a 2 plug connector for the distributer one blue wire and one black w/yellow, where do these get tied into?

for the early birds

 

Well, the blue is your tach wire, and the blk/yel is your coil power, if I'm not mistaken? I KNOW the blue is tach. Just connect blue to blue, and black and yellow to black and yellow.

Can anyone help with these then?
