so how do I go about this? I'm trying to get my p28 to run. My hx is wired with a 5 wire and a four wire. I can't figure out which wire the p28 reads because I can't find a replacement 5 wire to plug in to see if the stock ecu clears code with a new 5 wire becasue the only five wire I can find costs $400. Do I need to re-wire or is there a way to by-pass and make the #2 4 wire port the main port.

guru's anyone this is driving me nuts

 

the p28 doesn't have capability to read the 5 wire O2 sensor. you will need to pin out and run a regular 4 wire O2.

 

can you explain the pin out prossess or show a diagram or pic. I don't have much experience with this, but am eager to learn how to fix it. If you have a web site that explains this topic that would be cool, too. thank you for your help!!!!!!!!!!

what is pin out? help?????? and does this mean I have to re-wire?

 

'pinning out' refers to moving, deleting, or adding wires to ECU connector in order to add circuits or remove them from the ECU. I don't particularly have any schematics on line but you may want to PM 'Katman' here on h-t and he can direct you to what you need online. it's isn't that hard to 'pin out' the ECU for the 4 wire O2.

Good luck

Sorry it took me so long to post a reply...

Fortunately, we've been extremely swamped here at our shop in KC, so haven't had much time for tech support.

 

I think I have figured it out I ordered a generic chip to fill the socket on my ecu and should have it by tomorrow, then I will splice it see what happens next!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
