In your pic make sure the writing on the switches is oriented towards the top. E1 goes on the right hand side with the Black wire on the top pin. On my panel it is labeled GRD (ground) if u look real close. The last pin should have the Orange wire on it. The E2 harness goes on the left side with the same color orientation. A will be the second pin down from the top. This is all looking at the solder side with the writing on the switches being the top of the board. Need any further help call me. 318-366-9955.
