So, I got my engine harness redone, with new grounds installed, sections of new wire soldered in, and all the unused emissions plugs trimmed carefully. This is the second time I've done the harness, and it turned out alright, but still a bit off on the lengths. Lesson learned from all this: dont fawk with it if it aint broke!
With some light modding, I managed to fit the Porsche 944 passenger seat(manual rails) to the driver's side FC3S seat rails. The seat is in decent shape, and is a LOT more comfortable than the stock pos. I also got a set of fresher stock seats out of an S4 just in case.
EDIT: No pics of the Koyo because I had to send the Corksport oil lines back, since they kinked and didnt fit right at all. Trying to find some temp lines in the meantime just to get the girl running again, lol.
