Help Me Please

Im having some major electrical issues with my fj40, mostly runoff from Tuttle. Does anyone have a schematic that I could borrow, I have a book from the parts store but it sucks. Im at about 12 hours trying to fix my brake lights and my wife is about to drive it off a cliff so she can see more of me than my feet.

Also, just in case your 40 has them, keep in mind that some after market brake lights are wired in reverse - I found that problem in the past. Took awhile to figure that one out.

I am not sure if the 74 has combined turn stop like my 73. If it does then you have stop light power goin thru the turn signal switch.

If any of you ever have you brake lights stay on, check the jam nut on the brake light switch to see if it has come loose and is keeping the brake pedal from coming all the way up.

There are a lot of funky little connections under the rear of an fj40. and the wires are of a rather small gage too.

There is also a conector on the right side of firewall were the harness heads toward the rear of the truck that can cause problems. Also a connector up in the dash, kinda above and in front of the radio, that I have had trouble with.

Gude Luck, Don P.
