I need too change right side grip on my 2005 heritage softtail any diagram thax,s

I'm sorry but I can't send a diagram via this site. I have no idea where I can get a diagram either.

But, to replace the throttle grip on your Softail, you'll see the not only are you replacing but you're replacing the throttle sleeve as well. This actually makes it easier.

To replace the grip, first loosen the throttle and idle cables as loose as you can at the adjusters close to the throttle grip. Then remove the screws that hold the two halves of the throttle switch housings together. Carefully seperate the housing halves as much as the wires will allow.

You'll see the cables coming up and connecting to the throttle sleeve. Each cable will have a ball and a ferrell on it. Work both cables loose and slide the throttle sleeve off the handlebar.

Now, lubricate the inside of the new throttle sleeve, the cable area of the throttle sleeve and the handlebar with fresh white lithium grease. Slide the throttle sleeve up on the handlebar and work the cables back into the throttle sleeve. Be careful not to lose the ferrells. They must be in there for the throttle to work properly.

Once you get the cables installed into the sleeve, put the switch housings together and install the bolts. Before tighten the bolts slide the throttle up onto the handlebar until it stops. Then back if off about 1/8 to 1/4" or so. Tighten the bolts. Readjust the cables leaving just a bit of slack in the throttle cable.

With the engine off, twist the throttle to wide open throttle and let go of the throttle grip. The throttle should snap shut. If not, loosen the cables a bit or back the throttle grip a bit further off the handlebars. The throttle grip must work correctly or serious injury or death may result. This job must be done correctly. It's not difficult just make sure it's right.

Good luck
