Finally got my new LED bulbs in the tail lights! But no flash with the standard flasher so I swapped in an electronic flasher. Now the blinkers work fine, but the emergency flashers don't work, and strangely the cruise control doesn't work now

Any ideas on how to fix this? The LED bulbs are great though!!!

I think there are two separate flashers for the hazards and the turn signals - one of them is on the front side of the cab fuse box and the other is on the backside of it.

I don't know if that will fix your cruise problem but generally if there is anything wrong with the brake lights the CC will not work.

Sometimes cheap led bulbs can be the issue. What kind did you get?

I got these JDM AStars from Amazon:
I have them on the front and really like them. I just ordered some load resistors thinking that might help. I'll try that in a couple of days and see what happens.

Thanks James. I'll have to see if I can find the other flasher. I got some load resistors on the way so maybe they will help.

Okay, I finally got everything working as it should! So here's what I used:

2 Flasher relays:
Front turn signals (amber) and tail lights (red):
Load Resistors (got 4, only used 2 on the back):
Front Corner Lights (amber):
License plate, dash, climate control, courtesy light on doors:
Everything works and looks great! Nice upgrades!

The older Ford's had 2 flasher units one in fuse box for turns signals, emergency flashers unit is over by the glove box.
