Need help with making my 78 steering wheel work on my 69 F2 50. Having issues making the horn work. Saw a thread with Mike and feel that he may be able to help me with this problem

 

It'll fit but the turn signals won't cancel.

There is a fix however and that is to accurately drill holes for roll pins so they do cancel out the TSS.

 

What do I need to do to make the horns work?

 

First verify that the horns work.

Second, verify the horn relay works. It is located aft of the starter solenoid.

Third, the horn system works via the horn button applying a ground for the horn relay. If depressing the horn button does not work, install a jumper wire across the steering coupler ("rag joint") and retest.

If the latter fixes it, the small copper tang on the coupler is broken. Fab up a jumper wire with an eyelet terminal on each end and install it to bridge the electrical gap.

 

It is on 1965/77's, but may not be on 1978/79's.

1978/79 F100/350, Bronco & Econoline with factory installed Speed Control: The horn relay attaches to the Speed Control amplifier, located on the inside of the firewall, adjacent to the fuse box.
