How did the older Fords with the Mechanical diesels run cruise control or did they not have it? Chris

The idi's used a vacuum servo and a small brain box.

Actually i think figured it out. I finally found the pin out for the ford cruise control connector.



The first number is going to be the CC pin number and the second is the ECM pin number. So that means 1-9, 3-35, 4-18 (& 36 because its a 6 speed), 5-31, 6-??? 24??? possibly a ground , 7-H.I.R., 9-28, 10-Grnd

Ok so i put my downpipe together this morning and drove the thing around. I cant get any more boost than 2 psi. And when it hit about 2.5 psi it bogs down and blows white smoke?? The only mod is the afc housing is slide and that was by accident. Also i am not running a wastegate actuator. mine was broke so i took it off and wired the little arm that comes off the housing in the up position? My turbo is flipped. I really dont know to much about these motors. Any help or pointers. ive read the tech. articles but that really doesnt help me to much sorry.

you wired the wastegate open? NO! wire it shut for now. its probably not spooling up the turbo AT ALL. im sure if you close down the wastegate you will get some boost and it will start to run like it should. it should only take you a few minutes to do and you should get more then 2lbs on a neutral rev.

I think i wired it shut but ill check on that when i get home. I can floor it and it runs great then bam it shuts down and pours white. Also what does the motor do when it defuels at 2200 rpm and what does it do at 2800 rpm that is stock cut out right?


JP are you messing with the cruise control this weekend still?

Ok guys the cruise control works in my truck now. like a champ:thumbsup Now i am moving onto the a/c. I kept all the wiring for the a/c but it is not working. I think it worked for a few seconds on the first start up but i am not sure. I checked the a/c clutch fuse it was good. Is there a relay? And would not haveing enough air across the condenser cause it to cut off? The blower fan workes and all fan controls/climate controls work. Is there a trick to getting this to work. I have the 6.0 compressor and didn't disconnect any hoses during my swap. Thanks for any help.

Yeah cruise was easy it hooked up just the way i have it listed on page three. So i have to have the tach for the a/c to work. Does it send a pulse signal or something or can i just wire it to a Power when key on source and make it work? My coolant temp sensor works fine it shows up on my dash and my livewire unit. Thanks for the help JP you got the cruise in and a/c working in your truck?

a/c yes, cruise not yet. got sent to louisiana before i could work on that..yes the computer needs to see a tach signal for the a/c to work.. i had the same prob when i first did mine, hooked the tach up and the a/c kicked on instantly!!!

Cool well i guess i need to gather up some extra cash and get my tach kit. Do you know of any way to get around the a/c thing. It may be awhile before i can get the tach kit. Can i bypass that all together? Do you know where the relay is for the clutch. Where in la in i live in lake charles. Thanks for the help once again

u would have to some how get some kind of tach sig to the ecm, it wont read correctly but might be enough to get the a/c to work, you could just try and use the dodge crank sensor for now...... im in thibodaux right now, working on pipeline

It does suck i hate when you work outside and by lunch you need a shower and a change of clothes becase you are soaking wet. I hate it when your boots get so sweaty you can dumped em out. But yeah i guess i am use to it ive been in it for 25 years. Still cant figure out the a/c nothing i try is working. I have power for the a/c comming into the ecm but can't get nothing out i guess that is why it takes a tach signal to send power out of the ecm to the a/c clutch. oh and there is no a/c relay it is all controlled by the ecm i went to ford and talked to the diesel tech. The ecm even reads voltage comming and going to the a/c system crazy.

Just wanted to give a little update. I have put about 6k miles on the truck since the swap and everthing is working great! I recemtly did a 4gsk, exhaust springs, and headstuds. I am waiting on my clutch from south bend to come in before i build my compound turbo setup. i am gonna do a s475 over a hx35. and i will be running sdx 5x14 injectors. and bbd delivery valves. i think it will be a fun ride. Also i did get the cruise control working and the grid heater to work also.
