I just ordered a cam sensor plug and a knock sensor plug from eBay. Got the two for about $18 including freight. I still need a oil pressure plug but that one is about $25 from the above site Lex posted and about the same on eBay. I'm in no hurry now that the TPS plug and harness is sorted. Plus labour will be another $150, like it was to fit the TPS and new plug, so I might hold off since the main issue is now fixed.
I have the ute booked in for PDR in three weeks time so need to try and not spend too much coin, as I have other things to pay for over the coming weeks. I'd probably be fine but just in case. I'm still waiting for the bill for the shed and I also need to figure out what to do about a retaining wall in the cut next to my new shed. Just don't want to run myself short lol....
Plus the annoying cold start lifter tic is starting to drive me nuts, which means I may end up getting so annoyed that I buy a new set and have someone fit them and that will take precedence over a couple of wiring issues that aren't really a problem right now......hahahahaha
