New to the threads here but looking for insight on solving this problem. Put in dunne rite performance mass air conversion kit with baumann tranny controller. Drove the bronco down the road before the conversion to reasure everything in working order as it was. Since doing the conversion i have lost my cruise control features. Spoke with the guys at baumann and have confirmed with me the eec IV and cruise module are seperate from one another. connectors are all good,fuses good, module was working as far as i knew until after conversion. checked vacuum and theres no leaks hoses are solid. any light on this situation would be appreciated.

 

Maybe something got knocked out of place doing the conversion. Have you checked all wiring under the hood? Isn't there a connection on the master cylinder for the brakes? Maybe something there

 

ill check it out, second look can never hurt.

 

What year bronco, and vacuum or electric cruise? I'm betting something is unplugged.

 

It is vacuum, ill check it out today sometime and let you folks know

 

any possibility of or heard of the vacuum device failing before? ive been over it a dozen times now all connectors are pushed in solid no frayed wires or cut vacuum lines

 

Well if its anything like the directional vents in an A/C system, one small leak and it won't work. Could be a pain to find

 

I'm not sure of you can with these truck or not but on my buddy's old jeep we gave little sprays of I believe it was ether in areas and when the truck revved up a bit then we narrowed down the area for the leak an sprayed in that area to get closer till we found it.

Not so sure of its a good idea or would work tho...

 

Just like with gas line. Soap. It will bubble

 

The hard part here is getting inside the vacuum hose so you can see the bubbles!!!!
