I think you need to use punctuation, paragraphs, and complete thoughts. I can’t understand your post, I would be willing to help but I honestly just can’t make out much of it Use your words ---

ya jake what the fuck , your phone sucks and i dont think anyone here speaks text…lol… hes got a p0141 code for the rear heater that he cant get rid of, and hes got 2 new sensors. im still on comp i cant fuck with it, so i told him to try and ask around here for now… basically its got 12v for the heater but the ground trigger from a5 or a6 apparently isnt working, who ever did this swap hacked a bunch of plugs off it could really use a new harness but im not sure if thats the whole issue. he did throw another ecu in that someone let him use for now and the same code came back, so its gotta be wiring related or just something i cant think of… and im really no help aside from saying here check this, at this point…lol…i know theres some honda guys around on here so its worth a shot, maybe someone else came across this before… basically at this point, if the heater code goes away it can get stickered, since its allowed 2 monitors being a 96. but the o2 monitors should set, itll just be the catalyst monitor will set a code eventually from a punched cat… he just had to get one that needed to be plugged in…lol… ---

Try a rear sensor spacer if it’s throwing a code for a gutted cat ---

sounds wiring related to me. get another harness, and try that. or if you cannot find another harness or dont want to buy one, get a pinout diagram and just splice into the appropriate wires for the o2 and run new wires. and then solder the old plug to that. if that doesnt solve your problem if youve got the spark plug non fouler trick your sol
