k I just finnished my LSvtec I have a 99 LS with a 00b16 head on it. Im running a Ls 0bd2 to obd1 harness but I think the harness is wired for vtec so I just pined the vtec wire to to the correct spot one the engine harness. but hear is the part that im confused abought when I tryed to run the oil pressure wire on the p28 the oil pressure spot is D6 for obd1, but when I follow the wire through the jumper harness is gose to the spot right next to the obd2 oil pressure spot. wtf? so when I un-pin the wire that comes from the engine and put the new oil pressure wire in it throws a code I think it is code 90 but it might be throwing more than one. It also dosent throw anycodes when I have it hooked up without the oil pressure?

Im using this page for the diagrams
