B&M 70244 CONVERTER LOCKUP CNTRL - Manual (Page 2)

STEP 3. Connect the Red wire to +12V
power source and the Black wire to
ground connection located in STEP 2.
Reversing the polarity of these two wires
will damage the Converter Lock-Up
Control module and VOID THE WAR-
RANTY. Route wires so they cannot
become tangled in any mechanisms
(brake pedals, A\C, heater controls).
STEP 4. Route remaining wires from
the Converter Lock-Up Control mod-
ule to the transmission. Make sure
wires passing through the fire wall or
floor pan are adequately protected
against abrasion with the sheet metal.
Also take care not to route wires near
hot exhaust pipes and high tension
ignition wires. The heat will melt insu-
lation from wires and the ignition pulses
can cause unpredictable Converter
Lock-Up Control operation.
STEP 5. Disconnect the speedometer
cable at the transmission end. Install
the short adapter cable supplied with
kit on the transmission making sure
cable core is engaged in transmission
fitting. Next install the speed sensor
and connect speedometer cable to the
other side. Rotate sensor so that wires
do not hang down and are out of the
way of any moving mechanism or hot
pipes.
STEP 6. For most applications con-
nect the Yellow wire as shown in
Figure 1 which shows the proper wir-
ing hookup for the Converter Lock-Up
Control. This diagram shows the stock
TCC (Torque Converter Clutch) and
brake light switch with the yellow wire
feeding through the switch and con-
tinuing down to the ‘A’ terminal on the
connector going into the transmission.
For ease of convenience, the kit is
supplied with the yellow wire and a
black grounding wire attached to a
connector that will plug directly into the
transmission. This yellow wire can be
cut and routed to the brake light switch
and then continue to the Converter
Lock Up Control. The short black wire
can be attached to a transmission pan
bolt to ground the circuit. In custom
applications you can bypass the brake
light switch, and you can plug the
supplied transmission connector di-
rectly into the transmission and ground
the short Black wire from pin D. We
recommend that you wire the Con-

Installation of the B&M Converter Lock-
Up Control requires hooking up only the
Red, Black and Yellow wires, the Black
(thin) and Red (thin) wires are already
connected to the speed sensor unit.
STANDARD INSTALLATION
STEP 1. Choose an accessible loca-
tion on the dash to mount the Con-
verter Lock-Up Control module. Us-
ing rubbing alcohol, clean the surface.
Remove the backing from the hook &
loop tapes and install on the Con-
verter Lock-Up Control module &
dash.
STEP 2. Locate ignition key controlled
5A-10A fused source of +12V and a
good chassis ground connection. Most
GM fuse panels have an instrument
section that can be tapped to supply
the Converter Lock-Up Control mod-
ule. Use a VOM (Volt-Ohm Meter) or a
test light to check the continuity and
voltage between the proposed power
source and ground.
INSTALLATION
Installation of B&M’s Converter Lock-
Up Control requires clear access to
the underside of the vehicle in order to
properly route wires and install speed
sensor. Raise the vehicle so there is 2
feet or more ground clearance.
MAKE SURE THE VEHICLE IS RIG-
IDLY AND SECURELY SUPPORTED,
JACK STANDS, WHEEL RAMPS OR
A HOIST WORKS BEST, DO NOT
USE JACKS ALONE.
WIRING REQUIREMENT
The B&M Converter Lock-Up Con-
trol is relatively simple to hook up.
There are five wires connected to the
Converter Lock-Up Control module
which are color coded and have the
following functions:
