2.
Route the white wire of the Control Head’s DC Power Cable from the back of the head to an area
near the switched ignition power source. At the back of the head, be sure to maintain a cable service
loop of at least six (6) inches.
3.
Cut a short section (6 to 8 inches) off the end of the white wire and strip each end of this short wire.
4.
Extend the length of the Time-Delay Relay’s white wire so that it reaches the white wire of the
Control Head’s DC Power Cable. Use the 18-AWG moisture-resistant butt-splice included in the fuse
kit and extra white wire. Extra wire is not included, but in most cases there will be enough extra white
wire from the DC power cable to accommodate this wire extension. Cut excess length from this wire.
5.
Crimp the male-tab quick-connect terminal to one end of both the short wire and the extended wire
from the relay. Refer to the respective wiring diagram at the end of this manual.
6.
Crimp the ATM fuse holder to the other end of the short wire. The holder has built-in crimpable
joints.
7.
Cut the excess length from the white wire of the Control Head’s power cable, strip it, and crimp it to
the other side of the ATM fuse holder.
8.
Pull enough of the switched ignition source wire out of its harness so one of the T-tap quick-
disconnect terminals may be attached to it.
9.
Two T-tap quick-disconnect terminals are included in the kit. Based on the gauge of wire, select the
proper terminal size: Red is for 22 to 18-AWG wire and blue is for 18 to 14-AWG wire.
10.
Attach the selected T-tap quick-disconnect terminal by fitting the wire into its wire groove and
snapping the two halves together with a pair of pliers as shown in Figure 9-5.

11.
Push the male-tab quick-disconnect terminal into the T-tap quick-disconnect terminal’s inlet until it is
fully engaged.
12.
Install the 2-amp ATM fuse into the fuse holder. It is recommended that a piece of electrical tape be
wrapped around the fuse connection to keep the fuse from being jostled out of the holder.
13.
Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe
is avoided.
