1997 F250HD 7.3L It is a May build so is mainly 1996 parts. Came from the factory with auto transmission but PO did manual swap. Truck had factory cruise control but never worked after the swap.
I found clutch safety switch missing so installed that and now it works as far as truck only starting with clutch in and other pins ohm good but it didn't fix the no cruise issue.
All the diagrams I can find are wrong so I am stumped.
Horn works and steering wheel brushes appear to be functional.
Brake switch has 12V in and out so I think it is ok.
Brake switch on master cylinder has power in and out so I believe it is ok.
All brake lights work since I read that diagrams don't show it but they are somehow tied into the cruise.
I believe the issue is in the clutch safety switch (CPPS) wiring as I only have power on one wire however my colors don't match my Haynes or online diagrams. Also, no where can I find if this circuit runs on hot 12V or ground. Some wrong diagrams show hot 12V coming in on the light green wire from the brake switch but others show a hard ground on the red/Blu wire.
Most diagrams say I should have red/LtBlu, Red/LtGrn, LtGrn, Gray/Yellow. I actually have Red/Blue, White/Red, Tan/Blue, White/Brn. The White/Brn has power coming into the switch.
The connector for the automatic transmission column shifter is disconnected and the shifter was removed. I read that this needed to be jumpered to the tan/blue wire after a conversion on the CPPS but only on 2002 and up trucks so I don't think this affects me. That plug is for overdrive cancel.
Does anyone have a good diagram for a manual shift, diesel cruise control circuit that shows my color wires on the CPPS?
I have had this truck 2 months and have fixed everything except this and will be making a long trip soon so cruise would be nice to have functional but I am stumped.
Thanks.

 

Sorry, I can't seem to find any detailed diagrams on the 97 cruise control system.
