dose a 70 F-100 have two hot wires to work the brake lights ?

 

you should have a red/black wire comin from th column and one from the fuse panel going to the brake switch,

 

Yes there are two seperate wires going to the rear. The reason there are two wires is, the part of the bulb that is the brake light in the rear, is also the turnsignal bulb. This part of the bulb has double duty as the brake and the turn light. What combines the turn flasher signal and the brake signal power from the brake switch is the turnsignal switch.

If the turnsignal switch is in the center position, then the brake signal is put on both rear wires. If the turnsignal switch is moved to the left, the the turnsignal switch puts the left brake wire onto the turnsignal flasher, but it leaves the brake signal on the right rear wire. It does the opposite if the switch is moved to the right.

 

are there two hot wires or just one ? on my turck the wire feeding back to the brake light from the brake switch is yellow with a blackstrip then crosses over to the right side of the truck from a plug ???

 

some one changed the column from manual to auto the wiers coming from the column to where it pluggs in where spliced in so big prob. there ?!!does anyone have or know where i can find a skematick on this ????? thanks for you help.....Mt. man

 

I don't have a 70 schematic. You will also have to figure out what year column you have.

This wiring is not correct. There are two seperate wires going to the rear.

Here's a schematic for a 71 car. The colors may be the same.

Yes they made them back then. Here's proof.

thanks man i can't tell you how much that helps. if this does'nt help it's a start so thanks

 

I have the 1968 Ford Truck Diagrams and the colors are LT Yellow and RT Green for the rear.

If it is wired like the 68 I can post a link to any of the 100+ pages.
I would have to scan them in.

Here is a link to the 1968 Truck Lamp wiring:

Man i'm sure it's the same and if it is that whould be the best thing. and i whould be 4 ever indepted to you !!!!!

 

1967-72 F100/350's use the same neutral switch and stoplight switch, but the turn signal switch is different. 1967/68, early 1969 uses one type. Late 1969, 1970/72 uses another.

Since the column has been changed, here's one way to ID it:

All 1967/72 turn signal switches have Ford ID numbers on them.

C5TA-13341-B or C9TA-13341-A = 1967/68, early 1969

D0TA-13341-A = late 1969, 70/72

 

I posted a link for the 68 lamp wiring, if you cannot read it email me your email address to:

and I will email it to you.
