Lingenfelter L460021105 Lingenfelter PWM-001 DTOP Limiter TBSS H3 Hummer v 3.1 - Manual (Page 2)

Remove the 4 screws that retain the cover. Inside the module you will find a rotary switch. For
most applications, start with the indicator inside the PWM-001 set to the “B” (92%) setting and
decrease to “B” or “A” if the “Stability Control” message still appears on your dash.
On most vehicles, the delivered torque diagnostic is set when the delivered torque exceeds 92%.
Consult your vehicle specific diagnostic information to determine the correct setting.
Vehicle specific instructions:
2006 Trailblazer SS
Cut delivered torque signal wire coming from ECM on pin 38 of C3 connector (gray connector)
Can also remove pin B10 at Underhood Fuse Block & connect at that location (new pin required)
Should be TAN/BLACK wire (on circuit 464)
Green wire on PWM-001 goes to ECM, blue wire on PWM-001 goes to EBCM
Can cut wire anywhere in circuit between ECM and EBTCM
System needs power and ground so connecting in near underhood fuse block is recommended.
Red wire on PWM-001 goes to a key on 12vdc power source, black wire goes to battery ground.
2007 Trailblazer SS
Cut delivered torque signal wire coming from ECM on pin 12 of C3 connector (gray connector)
Can also remove pin B10 at Under hood Fuse Block & connect at that location (new pin required)
Should be TAN/BLACK wire (on circuit 464)
Green wire on PWM-001 goes to ECM, blue wire on PWM-001 goes to EBCM
Can cut wire anywhere in circuit between ECM and EBTCM
System needs power and ground so connecting in near underhood fuse block is recommended.
Red wire on PWM-001 goes to a key on 12vdc power source, black wire goes to battery ground.
2006-2007 H3
Cut delivered torque signal wire coming from ECM on pin 34 of C3 connector (gray connector)
Should be TAN/BLACK wire (on circuit 464)
Green wire on PWM-001 goes to ECM, blue wire on PWM-001 goes to EBCM
Can cut wire anywhere in circuit between ECM and EBTCM
System needs power and ground so connecting in near underhood fuse block is recommended.
Red wire on PWM-001 goes to a key on 12vdc power source, black wire goes to battery ground.
Additional notes:
The PWM-001 will disable the ability of the vehicle to perform a short circuit diagnostic on the
delivered torque signal. If a problem occurs that requires testing for a short circuit in the
delivered torque circuit, set the PWM-001 to the “Pass Thru” position (position F). Selecting this
position disables the PWM-001 and should be equivalent to removing it from the system.
