Did a search couldn't really find anything. As stated I have a 99 tj se that was swapped to a 4.0L and the motor is from a 2001 tj and the computer is supposed to be from a 2000. I am having the cel on with p0130, p0136. The wiring in the front has square harnesses and the wiring in the rear has round harnesses (which appear to be discontinued after 2000). My tj has 4 sensors on it as well. The front upstream (0130) is denso and the rear 0136 I'm sure is stock ngk. I'm going to replace them both with ngk but don't know which year to buy for. The rear I kind of have to go for 2000 parts I guess because those are the only connectors that seem to match.
My main question is do I buy all 2000 parts to match the computer electrical components or do I base it off of the motor. This is starting to aggravate me as I am coming up for Inspection soon. I already have a 2001 ntk sensor in upstream rear that isn't throwing a code so I guess that is okay by that wasnt throwing a code (even when a bank 1 sensor 2 was rigged to fit there before I put the ntk in.
