Installing the Toyota Shift Lever DIY Harness - 36012 DIY

HGM provides a “Do It Yourself” harness, 36012DIY, for COMPUSHIFT 3 Toyota AB60, A750, and A650 transmission applications.

This allows customers who do not have an factory Toyota shift lever to still use most of the features that the factory levers offers by wiring in a switches and indicators.

The main COMPUSHIFT harness to the various transmissions all use the same connector that mates to an intermediate harness that then connects to the various factory shift lever types. The DIY harness provides flying lead connections as needed from the intermediate harness connector to selected switches and lights.

Below is a table of the pinouts on the connector, the supplied wire color, and some notes on how to use each.

Terminal	Function	Wire	Length (in)	Notes
A	+12 POWER	22GA TXL RED	36	Provides +12V fused power to the park release circuits and lighting systems in the factory shift lever. Generally unused in the DIY configuration
B	D3 INDICATOR	22GA TXL PURPLE	36	Provides +12V power when the shift lever is in the D3 position.
C	D2/D1 INDICATOR	22GA TXL WHITE/GREEN	36	Provides +12V power when the shift lever is in the D2 and D1 positions.
D	+12 LIGHTING	22GA TXL LT BLUE	36	Normally connects to the lighting circuits in the factory shift lever. Generally unused in the DIY configuration
E	BRAKE SWITCH	22GA TXL GREEN	36	Normally connects to the brake switch in the factory shift lever for park release. Generally unused in the DIY configuration
F	SHIFT DOWN	22GA TXL BROWN/RED	36	For sport shift transmissions, a momentary switch to ground will downshift or range select down. This switch is usually unused in gate shift transmissions.
G	SHIFT UP	22GA TXL BROWN/YELLOW	36	For sport shift transmissions, a momentary switch to ground will upshift or range select up. This switch is usually unused in gate shift transmissions.
H	S-MODE SWITCH / OD CANCEL	22GA TXL BROWN/WHITE	36	For sport shift transmissions, a switch to ground selects sport mode instead of range select mode. For gate shift transmissions, a switch to ground selects overdrive cancel.
J	GND	22GA TXL BLACK	36	Ground for switch and indicator circuits
K	GND	22GA TXL BLACK	36	Ground for switch and indicator circuits
L	GND	22GA TXL BLACK	36	Ground for switch and indicator circuits
M	PARK INDICATOR	22GA TXL BLUE/ORANGE	36	Provides +12V power when the shift lever is in the park position.
N	REVERSE INDICATOR	22GA TXL BLUE/RED	36	Provides +12V power when the shift lever is in the reverse position.
P	NEUTRAL INDICATOR	22GA TXL BLUE/BLACK	36	Provides +12V power when the shift lever is in the neutral position.
R	DRIVE INDICATOR	22GA TXL BLUE/YELLOW	36	Provides +12V power when the shift lever is in the drive position.
S	S-MODE INDICATOR	22GA TXL WHITE/ORANGE	36	Provides 20mA of +12V power when the transmission is in sport shift mode.
