Installation
Schematic views in the same order as a hardware manual: power first, then injectors and coils, then sensors and CAN.
power
Battery, ignition switch, main relay, ECU +12 V and power grounds.
injector
Saturated injectors, switched 12 V, low-side drivers.
ignition
5 V logic-level coil-on-plug wiring. Do not wire dumb coil negatives.
sensor
0–5 V MAP on Analog Volt 1 with 5 V supply and sensor ground.
sensor
TPS / pedal 0–5 V on Analog Volt 2 (and 4 for dual).
sensor
Two-wire NTCs on Analog Temp 4 (CLT) and Analog Temp 2 (IAT).
trigger
Two-wire VR crank on VR 1+ / VR 1− with optional shield.
trigger
Three-wire Hall crank on Digital 1 with 5 V or 12 V supply.
etb
H-bridge motor, TPS 1/2, pedal 1/2.
can
CAN H/L, 120 Ω termination, dash / wideband / TCM.
sensor
Analog 0–5 V AFR or CAN wideband controller.
output
Low-side 16 pump relay, Low-side 15 fan relay.
