Ooh. Great advice. Thanks. I kind of wondered how to clean the hose after emptying black. Separate questions:
1) I hooked up today and have a blown bulb in tail light. Replaced it, no problem....then left turn signal caused flashers to start. Figured out that the two blades (for the 1157)were touching. I went to fix that and one broke loose from the plastic housing. I think I got it back in/on where it would work, but now I get NO lights on the back of TT. Checked fuses at panel (under refrigerator in mine) but all look good. Are there fuses somewhere else? Is there a separate fuse for the tail/brake light send on the 7 pin in my F150?
2) replaced the bulb in the light ont he front of TT by the tongue, but it still doesn't work. The switch on it could be bad, but is there a switch inside TT that supplies power to that light?
3) one more-if I insert my Equal-i-zer all the way in it will reach to the 2nd hole on my hitch. Better to push it all the way in, or stop at the first hole? Seems like the 2nd would be stronger, but it does draw the TT a few inches closer to the truck.
