I have a 68 f250 and im having problems getting the turn signals to work with the brake lights properly, when I got the truck both turn signals worked right but only the passenger side brake light work, I tried getting the drivers side brake light to work, (which I did) but then when I turned on my right blinker both of the signals would blink, and I tested the wires, one wire has brake light power and right signal power and another wire has the left signal power but no brake power, and I cant wire it up to work right in order iv'e tried all kinds of ways and looked all over the internet and cant find the right answer, any answers will be greatly appreciated, thanks

YOUR VEHICLE DOES NOT APPEAR IN THE ON-LINE REPAIR MANUAL I HAVE ACCESS TO (TOO OLD)

COMMON PROBLEMS WITH OLDER SYSTEMS. YOURS. MY JEEPS

ARE NO "GROUND". WHETHER IT BE IN THE "ANCIENT SOCKET" OR THE HOUSING ITSELF (2 LIGHT BLINKING DIMLY IS SORTA THAT SYMPTOM)

IF THIS IS A "DRIVER". NEWER SALVAGE YARD SOCKETS MAY BE "McGYVER-ED" IN, TO SOLVE THAT PROBLEM. RUN NEW GROUNDS TO YOUR HOUSINGS, MAY ALSO HELP.

I'M HERE TO ASSIST WITH ALL OF MY MIGHT!

MOST OLDER STUFF IS BASICALLY WIRED SIMILAR. IF YOU CAN "TEST" WIRES, TO DETERMINE WHERE THEY "COME FROM, OR GO TO".I MAY HAVE SOMETHING THAT MAY HELP.

YOU MUST ALSO, BE OPEN TO THE TURN SIGNAL SWITCH, AND OTHER ITEMS CONTRIBUTING TO THE PROBLEM.

HERE'S THE KICKER!

I PAINSTAKINGLY "COLORED" A '79 JEEP CJ."PLAIN JANE" WIRING DIAGRAM IN "MS PAINT". BLACK LINES, SIDE BY SIDE, WERE JUST WAY TOO CONFUSING!

I USED IT A "GUIDE" WHEN I COMPLETELY WIRED MY '46 WILLYS.'COURSE IT WAS STILL BLACK AND WHITE IN 1991. IT'S ALMOST IDENTICAL TO MY '77 CJ 5. SO YOU MAY HAVE AN ADVANTAGE!

THE "COLORS" WILL BE IRRELEVANT, BUT YOU CAN EZily FOLLOW THEM TO THE PLACES THE GO TO. EVEN THOUGH THIS IS AMERICAN MOTORS, THEY COMPILED SYSTEMS FROM DIFFERENT MFGers TO MAKE THEIR JEEPS.A BRAKE LIGHT SWITCH---IS A BRAKE LIGHT SWITCH, I DON'T CARE WHERE YOU COME FROM!

THIS DON'T HOLD TRUE, WITH THESE MODERN COMPUTER CARS!

LET ME KNOW IF YOU ARE GAME.I WILL SEND YOU A MESSAGE, IN "MESSAGES". YOU CAN SAFELY GIVE YOUR E-MAIL TO ME THERE, NOT HERE, FOR THE WORLD TO HAVE!

I WILL POST 'EM HERE. PROBABLY HARD TO READ. MUCH BETTER IN EMAIL

YOUR TURN
