I have recently performed this upgrade to my Canbus car (very pleased with the results by the way)
And am just about to change the oil pressure sender unit over, which I picked up from the OPC the other week.
This has led me to a couple of questions which don't appear to be answered either in Jon's write up or in the Pelican Parts article.
One is straight-forward and will be useful for me and for anyone else doing this mod: Namely, where exactly is the oil pressure sender unit located? I cant quite place it from the photos, Jon says to remove the 'belt' engine cover from behind the seats, but the Pelican Parts says to remove both this cover and the main 'Top' engine cover, so that doesn't really narrow it down, if anyone can confirm which cover is best for access and if I am then looking on the right, left or top of the engine that would help me greatly. Although It might be clear once I remove the cover(s)? be useful to know where to start anyway.
My next question is a bit more pedantic and apologies to everyone who thinks I'm being a bit an&I here. But what colour should/would the new wire, running from the G connector in the unit to the instrument cluster be on a 996. Looking at the photos on PP I can see Green/White stripe (which seems to be the same as connected to the WK connector, so I would want to avoid that really) There are also lots of pics of Yellow wire and one of a Solid Green wire (might be a covering sheath) when clicking on the additional pictures bit. If I had lots of electrical wire lying around then I probably wouldn't be too bothered and just use what I had, (what I assume they did) but I don't have any, so will have to buy some specially for this job, so why not get some in the correct colour code. Anyone able to help?
