PS- I need to know for a friend that has an S5.

 

hey guys i messed up, i mean the yellow wire not the white one.

i cant figure out where the yellow wire goes plz help



lets see:

rpm switch-45
electric ap-18
12v relay-6
vaccum line-?
wire-2

its not a pricy project at all

 

black ground, red to 12v source, white tach output. yellow to active something, grey to turn off something

 

but where does it go? (yellow wire) what does it hook up to?

it says on the directions, yellow is open an provides a ground for a circuit upon reaching the selected rpm limit.

what does this mean?

i understand the gray hooks up to the relay an gives the singnal to the ap, but the yellow i have no idea...

i keep thinking about where the gray an yellow wire goes, an i kno the gray hooks up to the relay but would that mean that they both connect together(then connect to the relay) so they turn it on/off?

i think that would make sense. i just dont want to fry something.

plz get back to me so i can get this thing working.
