As most of you know I have had a lot of electrical problems with my 70 F-350 since I bought it in Sept. I finally got the brake lights and turnsignals working good. The 4-ways used to work but after I got the turns and brake lights working the 4-ways stopped working. Perhaps I bumped something. Yesterday I started the truck and tried the 4-ways and they worked!. Today I moved the truck and cleaned off the 4 inches of snow we got and the 4-ways did not work.

Here is my thought: As I reported in an earlier thread I ran a separate wire for the brake lights and put up 2 new lights for the brakes. The existing lights I kept for turns and tail lights. The 4-ways when working use the original turn and tail lights. Would it work to run a new wire from the 4-way switch and splice that into the new wire I put in for the brake lights? This would be easier than trying to find where the loose wire or short is for the 4-ways with the existing wire. I am assuming the 4 ways would not work when the brake lights are on but I am OK with that if PA inspection is OK with it.

What do you think? Thanks!
