Ground wire/ heat kit

[Hidden 1]

On a amana heat pump system ,at the heat kit ground ,can i run a green ground wire to there,off the main ground lug, that the unit has at incoming power ? Or does it have to have its own.
An if ground lug is large enough can u ground 2 wires in it or does it need to be changed to a double lug .?
Resizing pics..

Supply house didn't write it on the invoice? They should have them. Not on the box it came in?

If its not on the front panel or sides have no idea . Contact them. Is there a wiring diagram should have a factory publish number on it might help them.

Where should i look for factory tag? Near the refrigerant lines? Its nowhere in the main 2 servive cover areas.
Also.if i have a e heat option on stat should i wire direct brown to brown an white to white ,instead of tying brown an white to stat white
Thanks .
[ wondered also -have u ever seen purple at unit,to yellow stat wire before -where unit has no yellow ]
Getting pic
Thanks!

There's not a wiring diagram on the inside of a panel? Transformer and a relay or a electronic board ?

Its got a defrost board ..typical goodman one..exactly like one in 1st pic.I took sides down an couldnt find a permanent tag..MAYBE I JUST AN NOT LOOKING IN THE RIGHT PLACE ?...
This diagram looks similar ..an has the purple wire at stat like mine ,not yellow..

Wiring diagram can't read the find print. Thermostat is lower right of the control board and has the colors for r,g,w,c,o,y which will correspond with thermostat. If in cooling and heat runs either move wire to b to o or o to b. Change thermostat in set up if terminal is marked ob. 28 jpeg your red arrow looks like that's heat. Can't read it.

Here are a few better pics ,i have to resize em ,getting more .
looks like one diagram i found uses purple wire to Y on board . ...an at end ON DIAGRAM PAGE 47 uses purple to yellow ..where the stat wire connects in
But board looks a bit different on diagram..
Page 47
Left 2 arrows show purple an yellow..Purple goes to the harness an other purple beside it in harness ,goes to Y at defrost board

No i haven't seen a purple wire before for cooling. In cooling the reversing valve gets energize. W2 turns on electric heat look at pages 17 & 18

Yes ty.
Its odd but yes,in that diagram its purple to the stat -Y .
Should i keep white an brown direct to same colors vs tying together to the white off stat wire ..so i can get the Emergency heat directly -brown ..?
I guess theres really no other choice but to go with the last wire left- purple ....

The only wire colors that are mostly standard from a manufacturer is the control transformer primary side white common, black 120, red 208 and orange 240. Thermostat wires if they run genuine stat wire with the correct numbers of wires.
Brand and complete thermostat model number?

Its a touchscreen visionpro ,like 8000 ..
Has w- white ..an x2 - brown both on left side..
Is the double 50 breaker w #6 wire to the 9.5kw heat kit fine? Im sure the double 30 for cool is fine ..[ pic is old wires before hook up ]
