I need a diagram for the heater terminal block (8 pins) I lost mine while waiting for elemant.

Your dryer is made by Whirlpool and you can find a manual among this group of them here: https://dl.dropboxusercontent.com/u/...l%20Dryers.zip
It is super easy to wire the elements. If you have two or more they are usually wired in parallel so that each one gets 240 volts. Use a meter to check your safeties in the dryer so that you do not have to do it twice, and make sure to change the belt and lubricate all bearings with white lithium grease (hi-temp grease). Good luck.
