Can the 2001 behind the dash wire harness work with the 2003 harnesses including 3.6L engine, engine harness, rear harness, dme 7.8, immobilizer, etc
This is a swapped 3.6 car that was functioning properly in an earlier 2001 race car. Had to Retub the car and move all the harnesses to donor 2001 chassis. Moved everything except the wire harness behind the dash.
The car starts and functions except water temp gauge on the 2003 cluster connected to the 2001 wire harness behind the dash. Also durametric recognized the cluster as an earlier cluster and not the k21 (3.6l) cluster.
Any help will be appreciated.
2002 C2, 95k miles, original exhaust and O2 sensors.
A few months back the CEL went on, Durametric says P0420: Porsche fault code 40 - Cat. conv. efficiency bank 1. CEL has stayed on so I investigated further. Pre- and post-cat O2 sensor voltages shown in attached charts, upper chart for Bank 1 and the lower for Bank 2. Warmed up the system at idle, then throttled up to 2.5 - 3k three times, two short, one long, during which time all sensors went near zero.
It looks like Bank 1 (upper chart) post-cat sensor is showing a problem while Bank 2 (lower) looks fine. (I started capturing Bank 2 after Bank 1) Also for a few years there has been a little rattling on the driver's side exhaust which I've suspected is a failing cat, but the exhaust system has not been recording any faults until now.
After having read a few related threads, it seems fairly certain that the Bank 1 cat is failing, perhaps with a loose element that reduced cat performance after the third throttle bump in the charts below. I'm leaning that way because it appears the sensors are all reporting data at about the same rate, oscillating when expected, except for post-cat Bank 1's sensor which begins the capture looking like it is largely reporting correctly but ends with oscillations that shouldn't be there.
There has been no perceptible change in performance, and I have over a year until the next smog inspection, so there's time.
Does this information indicate a pretty strong likelihood of a failing Bank 1 cat? Or are there additional diagnostic steps I should take to eliminate other causes?
2002 C2 manual:
Problem: when parked outside in freezing temperatures, oil leaks from the lower oil pump connector, item 7 in diagram below. When parked in a warm environment, it remains dry.
Anyone had that problem? Should I replace the gasket #8?

For anyone wanting to know how to remove the front and rear seats as well as the front driver/passenger seatbelts... this is the video for you! 😎 It was fun trying to figure out how to do this. Hopefully this helps anyone trying this. I would say removing the seats is 2/10 for difficulty, the side panels maybe 7/10 and then ultimately the seatbelts themselves a solid 5/10. Hope this helps! Should be more or less the same for the 996 and 997.
