Brian---There's an illustration of this in the new TRF "Green"
Catalogue, as set up by Don Malling and associates.
Meanwhile, if yu just want a general route for the hose(s) it goes thru
a hole in the firewall, behind the windshield wiper bottle area. Then it
wends its way thru the passenger compartment into the wiperbox, where it
splits into two hose directions.
If no hoses are visable, I would start by taking off each of the black
caps under the wiper drive arms. (Where the washer fluid nozzles should
be) From there, push a clear tube down thru these holes and see where it
comes out. You may have to remove the cover for the wheelbox to continue
the hose(s) down where you can "Tee" them together. From there, thru the
firewall, on to the bottle.
We don't get a lot of usage for this piece of equipment here in So. Cal.
so my ventures into this area are somewhat dim. (I write this as I look
out into the rain!)
I believe the Bentley manual has some info on this also.
I can't figure out the washer hose routing for a 1972 TR6 (CC79085).
Can anyone help with this seemingly trivial problem?
