Duplicate Cells in different columns and different rows

[Guidestone]

I'm making a wiring diagram/list in excel and need to find a formula for conditional formatting that will turn 2 cells red if those two cells in a given row appear anywhere else on the spreadsheet.

I already have 2 formulas for (Wire Origin and Wire Origin Terminal) and (Wire Destination and Wire Destination Terminal) that apply to their respective columns, but I have no formula to show if a duplicate occurs in another column. The two formulas I have now for conditional formatting are:

COUNTIFS($G$6:$G$155,$G6,$H$6:$H$155,$H6)>1

COUNTIFS($J$6:$J$155,$J6,$K$6:$K$155,$K6)>1


Below is my spreadsheet that starts at C5:

Wire #	Wire Guage	Wire Color Solid	Wire Color Stripe	Wire Origin	Wire Origin Terminal	Intermediate Fuses	Wire Destination	Wire Destination Terminal
1	14	Red	N/A	TB.1	3 (L+, 120VAC) 1	Fuse 1 (2A)	Power_Supply_1	L+ (120VAC)
2	14	White	N/A	TB.1	XO (N-, 120VAC) 1	N/A	Power_Supply_1	N- (120VAC)
3	14	Red	N/A	TB.1	3 (L+, 120VAC) 2	Fuse 2 (2A)	Power_Supply_2	L+ (120VAC)
4	14	White	N/A	TB.1	XO (N-, 120VAC) 2	N/A	Power_Supply_2	N- (120VAC)
5	14	Brown	N/A	Ground	Ground 1	N/A	Power_Supply_1	Ground
6	14	Brown	N/A	Ground	Ground 2	N/A	Power_Supply_2	Ground
7	20	Brown	N/A	CN.307	B19	N/A	Solenoid_Valve_1	N/A
8	20	White	N/A	Solenoid_Valve_1	N/A	N/A	CN.307	B8
9	20	Orange	N/A	CN.307	A7	N/A	CN.307	A8
10	20	Red	N/A	CN.307	A19	N/A	Solenoid_Valve_2	N/A
11	20	Lt Orange	N/A	Solenoid_Valve_2	N/A	N/A	CN.307	A7
12	20	Orange	N/A	CN.307	B7	N/A	CN.307	A9
13	20	Lt Blue	N/A	DB.1	1A	N/A	Solenoid_Valve_3	N/A
14	20	Red	Black	Solenoid_Valve_3	N/A	N/A	CN.307	B10
15	20	Orange	N/A	CN.307	B19	N/A	DB.1	2A
16	20	White	Brown	DB.1	1B	N/A	Solenoid_Valve_4	N/A
17	20	Green	Black	Solenoid_Valve_4	N/A	N/A	CN.307	B11
18	20	Orange	N/A	CN.307	A11	N/A	DB.1	2A

I need a formula for conditional formatting that will turn the BOLD example above red when a duplicate occurs in any row of those sets of columns.

Also, this can only occur when those two cells appear in that order. For example, 2A should be able to appear to the right of DB.1 as well as CN.307 and not turn red. Thanks in advance for the help!
