These wire(s) are in your vehicle’s main ignition harness, usually located on the steering column coming
from the ignition switch. Probe each wire with your test light. The correct wire(s) will show +12V when
the ignition switch is in these 5 positions (ACC-LOCK-OFF-RUN-CRANK).
1. If your vehicle has only (1) constant power wire, attach the
RED wire from the 18-pin harness and both large RED wires from
the 4-relay harness to the constant power wire in the vehicle.
2. If your vehicle has (2) constant power wires, attach the RED
wire from the 18-pin harness and (1) large RED wire from the
4-relay harness to one of these constant power wires. Then
connect the other large RED wire from the 4-relay harness to the
second constant power wire in the vehicle.
Make sure to wrap electrical tape around all (3) fuse holders to prevent shorting to ground.
