anybody have a full wiring diagram for a 250 with 4sp on the floor? it would be greatly appreciated

next, whats this pump looking thin bolted underneath the dash, right behind where the radio sits

and where the defrost lever is, theres a disconnected plug( 3 prong, 2 veritical, 1 horz) whats that go to

and theres a wire thats been bypassed going to a switch, its green and has a rubber grommet that plugs into the firewall, reverse lights is all i could come to

The wiring diagram is a sticky in the electrical forum.. I'm sure I used that diagram for my 66.. If it doesn't work I have a printed copy of the one I found, I could dig up for you... Good luck
