Injection

Using old wires.

I need to look at the car but the diagram out of the online books page E-43

each injectors has a red wire for power via S2 relay looks UNFUSED!!!

To ECU

pin#30 White/red 5
pin#14 Light-blue/red 4
pin#32 Yellow/black 3
pin#33 Orange/white 2
pin#15 Green/white 1

on my car the 87 seems to use different colors or aged colors

TPS

TPS switch (need to get a motronic pot type)
L-jet Pin Wire Color Use number in setup ECIII pin
pin#18 Purple common TPS pin2
pin#3 Yellow WOT TPS5V pin28
pin#2 White idle GND pin26

IAC

will use the same pins the powered the heater in the old thermo type

one pin goes to the S2 power fuel pump/O² Orange/black

need to add a flyback diode between the pins.

L-jet Pin Wire Color Use number in setup ECIII pin
pin#34 Orange will be the IAC control INJG pin6

S2 Relay enable

it looks like l-jet pin#28 Yellow/red need to go to ground to enable the S2 double relay


Fuel Pump/O² Power Control

l-jet pin#4 Grey/green looks to high while cranking and will power part of S2 fuel pump/O²
