i tried to do the timming on my 94 ford f150 4.9l but i cant seem to figure out which wire to disconnect forr the advanced timing. it doesnt have vacuum hose to the distributor and if i disconnect wireing hareness to disributor it cuts off. Without the timing advance off #1 cylinder seems to be firing between 120 and 180 degrees off. i had to look under truck to find where the timing marker was.

 

You're looking for the spout connector. It's located next to the TFI module and may have black clothe tape holding it in if the truck has never been timed before.

 

Should look like this, on the fender wall on the drivers side.

 

thanks all, i shall see if works better when i disconnect it to do timing.

 

i looked at mine and the spout is capped off. there isnt a bright orange wire comming out the other side like in the picture. just a gray cap like thing.

 

there isn't suppose to be a wire coming out of it. just the way the pic turned out, looks like theres a wire. Unplug it

 

even after i unplugged the spout with the timming light on #1 cylinder wire the timming mark on the crank is showing underneath the truck. i dont know what to do to make it so i can line it up wit timming marks on top of crank?
