• Remove retention strap standoffs from cam cover stud bolts.
  

Step 2 Disengage coil wires at coil #2 and #3. Re-route from ABOVE the wiring harness to BELOW the harness.

Step 3 Re-engage coil wires routed below the harness and push harness to gain clearance at cam cover stud bolts.

Step 4
Position bracket under strut tower brace and wiring harness.
Install onto 3 cam cover stud bolts. Secure with 3 nuts (10mm flanged nut). Torque 5-7 Nm

Tip , to avoid dropping and/or loosing flanged nut, use magnetic socket to hold nut during installation onto lower stud. Verify clearance between bracket and coil wires.
