Hey guys I recently picked a 97 dx m/t that was a hacked together mini me swap that was blown. I pulled it out and did a proper y8 swap. I was told that the harness was already swapped from a 97 civic ex with vtec and was running p2p ecu... When I swapped the motor and put it all together had and extra plug behind the intake manifold that I had no place to put its the same plug as the knock sensor and iiac valve, so that's my first question is if any knows what it's for? Second parts was I got it all together and I'm blowing codes--- p0141,p0505,p0441 and p0325.. I don't think the O2 sensor code is a big deal and I'm changing it in a day or so cuz I tried already once with no change but think he sensor was junk. I'm worried about the other codes as to if there related to harness issues. The only other info I cN give is when first started I blew codes for the ftp sensor after some research I found that the p2p ecu was from a car the had it and mine didn't so to fix it I found out that the 97-98 detail had y8 engine without the ftp and ran an obd2 p28 ecu so I bought and it got rid of those issues... If anyone could help if much appreciate it... Thanks
