key on power help

i know which one it is i think but isnt their multiple wires coming from it?

 

[jcoatswo]

Oh I see, if they're all going to the same terminal they will all be hot at the same time. Meaning for your application any wire will work that is going to that terminal.

so any wire from the c255 plug into column? thats simple enough, so i could use two wires so that one wire isnt spliced into twice?

 

[jcoatswo]

No, not any wire. Any wire coming from from or going to the pin 4 terminal on C255. Sorry if I wasn't clear on the previous post.

I'll state at that picture and figure it out I guess now im more confused lol

bump for an actual answer im getting readings all over the board with this multimeter ive deduced im a dumbass and dont properly know how to use it which is probably true.

The ignition will put power to pin 4 when the key is in the acc. and on/run position. If you're unsure which pin on the connector is pin 4 all you have to do is set your mulitmeter to the setting "20" in the DCV section.

1.) See which pins have power with the key off and note that none with power will be used for your application.

2.) Turn your ignition to the on position and note which pins have power.

3.) Turn your ignition to the acc. position and see which pins have power.

So say (completely making these numbers up) that pins 1, 2, and 5 have power with your key off- throw these numbers out of the equation, you will NOT be using any of these pins.

Then say pins 2, 3, 4, and 5 have power when the ignition is in the on position. Again 2 and 5 are useless. So we've narrowed your pin down to pin 3 or 4.

Now say with the ignition in the acc position we have power to pins 1, 4, and 5. Remembering that 1 and 5 are no good, you have found pin 4 which is the one you want for the fans.

i just dont know which down there is pin 4, i have no test meter =( i almost spliced directly into the ignition fuse into the fuse panel but then though no thats hokey. alkso why does that diagram have a clutch switch i dont have a clutch

^ very good logic. haha

Its prolly a universal diagram and the have the wiring for both a manual and an automatic..would be my guess.
