Installing the Control Components
Best Practices
•
To confirm a good ground, use an ohm meter to measure the resistance
between the ground point and the negative battery terminal. Resistance
should be less than 1 Ω.
•
Route all wires to ensure they will not contact hot, sharp or moving parts
(including the park brake mechanism, steering column, and pedals).
•
Before drilling any holes ensure there are no OEM wires, hoses, or
components that may be damaged.
•
Do not use a test light to probe for power on vehicle circuits, the increased
current draw of the test light may damage components.
•
VMAC recommends using only sealed crimp and solder butt connectors for
all electrical connections.
•
To ensure a durable connection, use only good quality crimping tools.
•
Apply loom to all wiring:
Ǜ
Use high temperature loom in areas where high temperatures may be
expected.
Ǜ
Use spiral loom in areas with high vibration.
In-line Butt Splice Connections
•
Cut the wire approximately 2 in from the connector.
•
Strip approximately 3/8 in from the end of both sides of the cut wire, as well as
from the end of the wire being spliced in-line.
•
Twist the wire to be spliced in-line, together with the "live" side of the wire (not
the wire attached to the connector).
•
Slide the butt connector onto the twisted wires and crimp it.
•
Insert the "connector side" of the wire into butt connector and crimp it.
•
Lightly tug the wires to ensure they are properly crimped.
•
Using a heat gun, carefully apply heat to the butt connectors to seal the
connection.
