TR4/4A Windshield Washer Tubing Routing

OK...I guess I didn't take enough pictures when taking apart my car. And since I tore it apart over 4 years ago...I just can't remember. I'm trying to remember the routing for the tubing coming from the washer bottle to the pump, then most importantly from the pump up to the upper dash. I know the tube goes in the firewall, but does it just route itself randomly behind the dash to the pump or does it get tucked in the wiring harness clips as well? Then the big question, once it goes from the pump how does it go back up to the "T" by the wiper boxes. I know by the passenger access hole (where the black plate with four screws goes) there is a small hole for a grommet, but I thought that was for the windscreen flap rod for cool air. Or is that for the tubing? If it isn't for the tubing, how does the tubing get back there? Confused? Sorry guys for all the questions. And yes, just using normal Lowes bought clear plastic tubing unless someone can point a source for the proper off white tubing. Thanks!

Mine is loosely threaded. From the firewall it comes straight back and turns the corner by the dash behind drain tube. Then draped over the steering column and a bit of a loop to the pump. From the pump loose up the passenger side of the heater to the dash. Thats where I lost it.
