4.0 Quick Draw Installation

4.1 Mount the TCM

The TCM can be mounted inside the passenger compartment or in the engine compartment. If mounted in the engine compartment, follow these guidelines:

● The TCM should be located such that it is protected from water and road debris.

● The TCM should be mounted well away from exhaust manifolds or headers.

● The TCM should be mounted as far away from spark plug wires, CD ignition boxes, and other "electrically noisy" devices as is reasonably possible.

● Make sure the connector end of the TCM is pointed DOWN such that water cannot make its way into the ECU terminals.

● Do not over-tighten mounting hardware if the TCM is not mounted on a flat surface.

4.2 Wiring Installation

● The Quick Draw TCM contains multiple processing units that require a clean power and ground source. The wiring harness must be routed to avoid exposure to dirty power or ground sources.

● Keep sensor wiring separate from high-voltage or "noisy/dirty" components, especially:

○ Secondary ignition wiring (e.g., spark plug wires).

○ Ignition boxes and their associated wiring.

● Ensure that spark plug wires do not come into direct contact with wiring.

● Never bundle or loom sensor wiring together with high-voltage or "noisy/dirty" wiring in parallel. If crossing is necessary, wires should intersect at an angle rather than running alongside each other.

4.3 Power and Grounding

● The main power and ground connections must be made directly to the positive and negative battery terminals-not to any other connection points.

● Ensure the engine has a proper ground to both the battery and chassis.

● All wire connections should be properly crimped and soldered, with quality heat shrink applied over the joints for protection.

● Avoid using T-taps or similar connectors-use proper crimp connectors, solder, and heat shrink for all connections.

4.4 Additional Wiring Precautions

● Do not use the electric fan outputs to power the fans directly. These outputs should only serve as a trigger source for a properly sized relay that matches the fan(s) being used.

● Never splice or share signal wires (such as the Throttle Position Sensor (TPS) signal) between different electronic control units (e.g., "piggyback" systems). This can cause erratic behavior and unreliable sensor readings.

4.5 Main Power/Battery Connection

The Quick Draw TCM has a main battery power connector labeled 12V Battery + (red) and ground connector labeled 12V battery - (black) on the Main harness. These should be connected DIRECTLY to the positive and negative battery terminals.

If you have a "dual post" battery, it is advisable to purchase separate posts/studs to connect the TCM power and ground to the non-used terminals. Only use the fused power cable with the proper connectors supplied by Aces.

Do not connect to the TCM until after ALL wiring and installation is performed.

4.6 Harness Routing

If the TCM is mounted in the interior, the main harness will have to be routed through the firewall into the engine compartment. Use a 2" hole saw to create a hole in a desired location if no other point of access is available. Use a grommet for a 2" hole to seal this area.

If the TCM is mounted in the engine compartment, the cable to the 5" handheld will have to be routed to the CAN connector on the main harness (located near the TCM main connector). This will require routing the small CAN connector somewhere through the firewall.

5.0 Harness and Sensor Connections

The following indicates the primary sensors that are required to be connected. Each connector on the main harness is labeled with the sensor name. The name on this label for each sensor is in parenthesis below.

5.1 Handheld

The handheld plugs directly into the main harness at either connector labeled "CAN." This connector is located approximately 12" from the ECU connector.

CAN Bus connector

5.2 CAN Splitter

CAN splitters enable you to add an or more additional CAN devices to your Aces EFI systems, without the need to unplug the handheld. This easy-to-install wiring harness simply plugs into the CAN connector on your main harness-then lets you plug in any Aces EFI CAN device, such as a digital dash or USB to the CAN communication cable.

If you're already using an Aces EFI ECU such as the Jackpot to control your engine, connect the ECU and the TCM to the CAN splitter as displayed below:

5.3 Loose Wires

The following loose wires in the main wiring harness should be connected as follows on all systems.

● IGNSW (Red)Should be connected to a clean key-on/cranking +12V power source. Power source should only be active when the ignition is on (key-on power). Make sure the source has power when the engine is cranking as well (check with voltmeter). Not all sources apply power when the ignition switch is in "cranking" position. This wire is located approximately 20" from the ECU connectors. DO NOT connect to a "DIRTY" source like an ignition coil!

● 12V Battery + (Red) MUST be connected directly to the positive battery terminal. This powers the fuel pump and fuel injectors. This wire is protected by a fuse in a sealed fuse holder. The fuse holder is located about 8" from the TCM connector. A 20-amp (20A) fuse is pre-installed.

● 12V Battery - (Black) MUST be connected directly to the negative battery terminal. Using a traditional chassis ground can cause electrical issues with the Quick Draw TCM. This wire is located approximately 20" from the TCM connectors.

5.4 Additional (optional) Outputs

● Bump_down (Green) Once in manual mode, momentary switch to ground to downshift.

● Bump_up (Purple)Once in manual mode, momentary switch to ground to up shift.

● SPEED_OUT (White) VSS output.

● REV_OUT1(Green) Programmable ground output.

● CAL_SCL (Brown)The Quick Draw TCM supports two calibration modes. Calibration A is enabled by default and can be considered a street or daily driven calibration. Calibration B can be used for racing, off road, or aggressive shifting settings. When the brown wire is grounded, Calibration B is enabled.

● Tach_IN (Gray) A tach output from a sensor or module. This is the tach input for the TCM.

● TCC_UNLCK (Purple) (+12V) Switch to 12v to unlock Torque Converter Clutch. Normally connected to the brake pedal switch to unlock TCC when brakes are applied.

● Note: This function will prevent the TCC from locking under any operating condition while activated with 12v.

● TCC_LOCK (Yellow) Switch to ground to lock Torque Converter Clutch in 2nd-4th gear regardless of vehicle speed.

● Brake_SW (Blue) This can be installed to a +12v source. This input is used to unlock the torque converter.

6.0 Transmission Sub-Harness

6.1 Transmission Wiring

The transmission harness is compatible with GM 4L60E, 4L65E, 4L80E, and 4L85E transmissions. Each connector is labeled.

Transmission Harness

● Transmission ECU Connector (B1)- Plugs into the C4 connector on the Quick Draw main wire harness AH2020. Plugs into the last connector opposite the main harness.

● Main Transmission Connector- Plugs into the connector on the transmission on the driver's side of 4L80E (installed horizontally) and the passenger side of 4L60E (installed vertically).

● Vehicle Speed Sensor (VSS)/Transmission Output Speed Sensor (OSS) - Located on the rear driver's side on a 4L80E and the rear passengers' side on a 4L60E

● Turbine Speed Sensor (TSS) - The 4L60E does not have a turbine speed sensor. For 4L80E applications, it is located towards the front driver's side of the transmission.

○ NOTE: The 4L70E has an internally wired TSS, but it does not connect to the Quick Draw harness. In this configuration, the TSS is used for monitoring purposes rather than calibration.

● Brake Switch (Brown) - Wired to the brake light switch. This must be installed to a +12v source. This input is used to unlock the torque converter when the brakes are applied.
