What's the best way to lube the wiper motor? Did you attatch both lines to a two port fitting?
You can spray silicone in the inlet port while it's running ...or disassemble it and lube with Vaseline, etc.
The line routing is tricky. I ran my wipers to the vacuum/fuel pump inlet side, which then goes to a tee at the manifold where it joins the PCV. I also have vacuum assist brakes so have another tee fitting to that.
