Electrical:
The electrical portion of this is explained in the packet with the
relays that you received with the column.
Note: There may be a dark green wire left over when this
installation is complete. This wire is for the idiot light bulb. If this
is important to you, you can wire this green wire to a 2 wire toggle
switch. Then run an additional wire to a ground and connect to the
other terminal. This will make your idiot lights come on with the
switch so you can check for a bad bulb.
After the relays and wiring are set up and ready, secure the relays
up and out of the way. The relays have mounting tabs to secure
them. They do not need to be grounded individually. They should
be mounted and routed as not to interfere with the pedals or your
feet. It is not recommended to attach these relays to the heater box
as excessive heat will shorten the life of the relays. We found a
nice location up and to the left of the column on a structural gusset
for the firewall. Make sure the black ground wire is connected to a
bare metal surface for a good ground.
NOTE: It is necessary to secure the relays with the wires
pointing down! They are not waterproof and we do not want
them to collect water for any reason!
NOTE: THE RELAYS AND WIRING RELATED TO THESE
ITEMS ARE NOT FUSED! THEY RECEIVE FULL BATTERY
POWER AT ALL TIMES. Please proceed with caution.
Before connecting the plugs to the column… Make sure the key is
in the off position (Key only comes out in the off position).
There is a small plug with 4 wires coming from the column to the
relay pack, this is the ignition switch plug. This plug has a clasp
on it. We recommend that at first this plug is only lightly connected
without clicking it together completely. If there are any wiring
issues this is where they will become evident. The red wire will
be where this shows up. If this red wire gets hot… disconnect the
plug and verify that all wires are connected properly.
