I have a car here that we recently installed the GEN 6 on. It fired up and ran great. Sat for several days and now the injectors arent functioning. I already made sure that the battery was fully charged and still nothing. Accel's site does not have the wiring pin outs for this system anymore, only install instructions. Does anyone have a wiring/pin out chart for the ecm handy and possibly a wiring color chart. Any help would be greatly appreciated. TIA.
Does anyone have a wiring/pin out for thr Accel GEN 6

my old dfi had a jumper to use stock harness so no colors
if any one has a diagram it would be NORBS
from reading through the instructs i pulled this info out for pin outs
P1 C8 12 volts battery power
P1 C2 coolant sensor 5v signal P1 D2 coolant/ATS sensor sig return
P1 D10 ATS 5v signal
P1 D6 MAP 5 volt reference signal
P1 C3 MAP signal
P1 D3 map gnd
P1 D5 TPS analog 5 volts
P1 C1 TPS signal
P1 C5 O2 signal
Relay terminal R1- 3 12 volts O2 heater and fuel pump
P1 D4 O2 heating element ground
P2 B3 knock sensor signal (to esc output)
P1 C8 12v batt out for misc use
P1 D7 12v switched out for misc use
P2- A11 \
P2- A10 \
P2- A8 /communication port cable to laptop
P2- B8 /
P1 D15, D16, C15, C16 injectors 12v ... The batch fire spark and fuel ECU incorporates a series of 4 internal peak and
hold 4/ 1 drivers and has the ability to run 8 low impedance injectors at full duty cycle for short periods of time.
The SEFI unit is capable of controlling 8 low impedance injectors with no time or duty cycle constraints.
P1 D14, C14 injector ground
P1 D11 12 volts for fuel pump /o2 heater relay R1
note* P1 D11 is supplied with a 2 second prime signal to charge the fuel rail. If an RPM signal is not seen on terminal P2- A2 the relay is shut off. Once P2 A2 becomes active again, the fuel pump is turned back on.
P2 A2 ignition module RPM signal input from module
P2 B2 timing bypass (Est) 5v when above 400rpm
P2 B1 ignition timing control -to module
P2 A12 timing circuit gnd
P1 C12, D13, D12 C13 IAC control
P2 B4 TCC torque converter lockup (grnd when activated)
P2 B9 nitrouse mode input(when 12v applied )
