Here is a simplified diagram of the K-Series ECU (thanks to Carl - N77).

Which bit are you unsure about the diagrams, or the Cable Colours lists

Anybody have an oscilloscope. I am wondering if we can wiretap the 02 sensor feed and see what it outputs. We can then sample it build an O2 sim. We also might need the primary 02 feed to compare.

Any takers?

i reocn we can.. but the sim would have to fluctuate completely in phase and i think we would have to get the oem signal and then get the modded signal and then using osme resister knock its value down... its simple but might jsut work..?

Hi taz do you have the circuit layout for E connector?

Stanwan, I've got an ocsilliscope in my loft. What do you want to do with it???

Andrew

Taz, where did you get that book from?

- Kevin.

Can anyone let me know which wire is the speed sensor please?

Need to connect it to my gps (kenwood)

Also, is there a wire that outputs to the reverse light that I can take a feed from (low current) or should i take that from the loom?

it's ok - just spotted it - white/green. thanks

Hi,

Sorry this is still a bit confusing - trying to wire-in my VTEC indicator - instructions in Jap !

Only have 2 wires and earth - vtec wires on & off - which points?

sorry if this is the wrong section to ask - experience most welcome!

does anyone know which wire i would have to tap into for the 02 sensor sim for when you decat the car?

is it No-6-wht-Primary O2 sensor from connector A by any chance???

Cheers
simon

Please see the below links. They are diagrams provided to me by my local Honda Dealership. Hope this helps.

http://www.freepichosting.com/Albums/421573973/2.html (connector B)

http://www.freepichosting.com/Albums/421573973/3.html (connector E)

the above links would be handy but they aint working, has anyone else got them?

ignore that, there working now

My head hurts after looking at that

the links ain't working any more

Does somebody still have the info from links above???!!!

THEY ARE NOT FOR EP3.

People DO NOT use these pinouts!! You will damage your car/ECU. They are not for EP3 CTR. The lists don't even match the pics and CTR does not have connector C, which is for automatic transmissions (see the pin names). EP3 CTR has connectors A, B and E.

anyone got uk ep3 pre face ecu wiring pinout diagram ? found some online but don't seem to match my ecu so want to be 100% sure have right one

need to know which wires are

speed
rpm
can use as earth
can use as power for heads up display
