67 250se coupe cold start solenoid

[grezm0nkey]

Can anyone please help with my cold start solenoid? I need a wiring diagram to locate where the power comes from, to the solenoid.

i checked the switch(solenoid) with 12v and it clicks. also confirmed with engine running and engaged switch, engines blogs down with extra fuel injected. tested for power at wire when ignition key is turned to start. switch has a blip of power when key turned. i am not sure how long this stays open for the extra shot of gas. i am also not sure if switch opens in run and not start and for how long a duration. i dont know what tells the switch the engine is cold to allow function of cold switch.

wire runs from switch on the intake manifold and disappears into a bundle running along the firewall. not sure if it runs to a relay on the firewall or into the cabin.

Thanks in advance...........grez

The wire to the CSV comes from the switch/contactor side of the relay on the firewall.
This relay's coil is energized by a switched ground at the Time/Temp sensor at the block, just above the FI pump. It only works below coolant temp of 35C. If you ground the W terminal at this TTS , the relay should click and send power over to the CSV. It should do so for 1 to 12 sec., depending on coolant temp.
ONLY when starter circuit is energized.
