looking at my 89 the timer is mounted to the far right in the row of relays ( the truck's right) the only real big one. as for the nozzles, my 89's look the same as yours, but my 90&93 look like the one in the pic. I think the tips are missing but i may be wrong. other pic shows the firewall on my 89, see the sideways mounted base with no relay in it? I wonder if thats the one youre talking about. ONLY go with an OEM cap! the others fit like CRAP!!!
