i want to set up a 12 volt fuse block. basically it is a block with 6 points to hook up
looped wire terminals. it also has 6 grounding points. here is a link,

http://home.comcast....ck0/fuseblk.JPG

it can be used to hook up all my gauges and what ever else i need 12 volts for.
i basically want to run 12 volts hot when on and starting to a relay. then go straight
from the battery - to the other side of relay - to the 12 volt fuse block.

i need to know wher eto get the 12 volt source to trigger the relay.

thanks

I know there is no such thing as a 400M, but mine has a modified CAM.

This may not be right but have you thought about running a hot wire from the battery side of solenoid? This way it will only be hot when switch is on. You may want to get a second opinion.

well this is my first ford ever. i did not know there is a solenoid for the battery.
have a pic of what i am looking for? my friend is coming out to give me a run
down of the engine bay components. i have to get a chiltons or similar book.
that sounds like a good spot to get my 12 volt source.

Thanks

The solenoid usually is mounted on passenger side on fender wall near battery. It has the positive side battery cable on one side and the starter cable on other, along with ignition wire and others.

ok i looked at the starter solenoid. there are 4 connection points.
one for battery.
the opposite side goes to starter.
the middle 2? i have no clue?
i guess one comes from the ignition?
the other i dont know.

please let me know if you could.

Thanks

Not sure if I was sure, had to look it up and I hope I read it right, one wire comes from ignition switch, splits, one to solenoid and other to modulator. The other also comes from switch and splits, one to coil and other to solenoid.
