I have a 95 1.8 with a bp4w head, I'm trying to put a bpw4 throttle body on a skunk2 manifold so I can have a working iac valve
also for ic piping room it currently rubs. I have a na 1.8 throttle body on it and its very in the way and the iac remains useless.
hence why I want to change to bp4w
The problem I have is the tps sensor, the 95 has a 4 wire tps and the 99-00 has a 3 wire.
Ive seen other forums talking about switching from a 90-93 to a 94-97 but not to a 99-00
my understanding is I can leave the extra wire in the harness I'm just not exactly which wire is what and finding information about this seems impossible
If anyone could help I would much appreciate it

 

If this hasn't been resolved yet the VVT megathread covers it and also Car Passion Channels video and wiring images
