Sorry members to bring this back up, but I can not find the solution.
1986 c10 orig 305 carb converted to 70s 350 carb.
Just had my 350c rebuilt and all wiring seems to be intact. This has been an adventure cleaning up all wiring unuse in the bay and thanks to the people on this forum I have gotten this far.
Do I need to jump the egr bleed circuit to make tcc work.
Vacuum and brake switch verified working.
