The button is broken and I broke a wire off so my plan is to re wire it to a switch button but I cant tell which ones are ground and positive and negative there are three wires red yellow and white. Any one know

None of them are ground

 

1 should have 12v with key on.

 

the other two are the signal wires that operate the 2 solenoids that control opertaion of 4wd.

 

Signal to one = solenoid to activate 4wd

 

to the other = solenoid to disengage 4wd

 

Use a MM or test light to find the constant 12v

 

Then use trail and error to determine which is which for the others.

 

If you REEEEEAAAAALLLLLY need wire colors I'll check for ya tommorow.

 

 

This is for Manual trans. If this is an automatic I can't recall excactly the setup. Again I'll check up tommorow

Should be enough info to get it fixed

Gloyale is spot on with his description

the automatics work the same way.

 

Remember you will need a SPDT

(Single Pole Double Throw) switch.

I was wondering if you could tell me which wire colors are which. Mine is a 86 but has 4wd push button.

Howdy Bush,

 

you might consider telling

what type tranny you have (manual/auto)

 

 

and or

creating your own post

Hi Skip,

 

 

Thanks. I have 5SPD MT. Sorry, I saw the earlier post where it said just for manuals so yea. I appreciate the help though!

Well....

 

I did it myself.

 

 

If your hooking it up to a single pole, double throw switch (which you must), the white wire is the one in the middle.

 

 

 

Works well!
