Gary Lewis Posted September 18, 2018 Share Posted September 18, 2018 I actually have a tester for the vacuum speed control, my son used it to test the one on his 86 and I used it to test the one on my 1994 Taurus. Well, if I didn't have several of the modules I might want to borrow that for Big Blue, who's speed control doesn't work. But, that might have something to do with not having a vacuum diaphragm. Would that have anything to do with it? Link to comment Share on other sites More sharing options...

I was calling the servo the vacuum diaphragm - and BB doesn't have one of those. But, I have one or more in the attic. Link to comment Share on other sites More sharing options...

The rag joint has no bolts to connect the jumper wire to so I just hooked a small throttle return spring across the joint to complete the ground. Horn works fine now. Thanks for all your help.

Good idea! I was expecting you to go from the rag joint to ground. But instead you went across the rag joint and use the steering box as ground. Right?
