Step 5 – Connecting Cable

Determine connection points in the under-dash relay box for

all four wires before attaching any of the wires. When you

are sure of connection points, you may cut the Cable to a

shorter length, but be sure to leave some extra length. If

the Cable is too short, you can add extra length by carefully

splicing, soldering, and using electrical tape.

You can use the shop manual for your vehicle or access

online diagrams from online websites such as Mitchell 1

(Division of Snap-On™) at www.eautorepair.net

Usually the three connection points are available in the

under-dash relay block and vehicle chassis ground point is

nearby.

Ground (black) – Near the relay block you will find a

vehicle chassis ground bolt with numerous black wires.

Attach the black wire to that bolt and make sure the bolt is

retightened properly.

Ignition (white) – Using the shop manual diagram locate

the relay connection that provides a 12-volt level only when

the ignition key is turned On [called HOT IN RUN]. Locate

the relay coil connection (such as a back-up light relay) that

receives 12-volts when the key is On (will show on your

multimeter). Connect the S4 white wire to the existing

vehicle wire using one of the S4 Installation Kit wire

connectors to capture the vehicle wire and use pliers to

squeeze tightly.
