Need help with Econoline lights

Both my brake lights and reverse lights do not work. Rear lights do work when turned on.
I need to know where the brake light switch is, I assume it is on frame? cannot see it with the belly pan on.
The reverse lights, should they be connected to the trans or trans linkage / switch somewhere?
Could really use a complete wiring diagram for the entire truck as it was butchered by someone along the way.
Any ideas?
Thanks

Reverse switch should be like a push-button under the steering column brace.

brake light switch screws in to the master cylinder if you go to old econolines yahoo site there are wiring diagrams in the files section

Got the reverse light's working, they lost a ground to rust, sanded and replaced the ground. They are good to go.

Brake light's- found the switch, which is mounted in front of the master. It has two ends that were rusted, sanded them and replaced the wire ends, still no lights. Not sure if this switch is made to come off? anyone real familiar with it? The wires run across the van to the passenger side and look to go into a relay switch. I don't think the switch is bad because I do have rear lights, rear emergency lights flash and rear directionals work.
Any diagnoses or ideas where to look next would be appreciated, I think I am running out of ideas...
Thanks

my 61 switch screws directly into the mastercylinder napa carries them also rock auto online

donivan,
Followed your advise, put the wires together and as you said the lights went on! I took the switch off. I checked out what is supposed to be the correct switch on line, but it is not even close to the one that was on there?
Ordered the switch, autolite c60b-13480-a, hopefully I am gaining on it.
Thanks to all for your help! I'll update when the new switch arrives..

donivan,
The two switches are compleatly different. The one that came off the van attach's with a bolt through the switch. Where the one listed and the one I bought before taking the switch off attach's with threads on the end.
The one that came off is in-cased with a rummber covering that does say Fomoco and the switch is from autolite. So I am guessing that it is original.
I am sure someone here would know way better then me, but I guess unless you have had to change one there probably not to many people familiar with it.
I went to Mac and they don't list either, so the its kind of a mystery..

You have a 67... doh! Yeah, different switch due to different MC. Good job figuring it out though!!
