- block is now a S
- pickup will be VR on a 60-2
- COPS (Coil On Plug)
- cam trigger at some point but not yet
- use 164 intake(cut to fit) with the longer runners tuned to the S cams
- 179.91CID 2.949L
- stock injectors 18LB
- Req_Fuel 17.5ms
I guess I cut that in half 8.75ms
I changed the coil mosfet resistors to 1K (feeding the Base)and put in PNP 2N3906

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
| L-jet Pin | Wire Color | Injector # |
| pin#31 | Light-blue/yellow | 6 |
| 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
| L-jet Pin | Wire Color | Injector # | number in setup | ECIII pin |
| pin#31 | Green/yellow | 6 | INJF | pin18 |
| pin#30 | White/red | 5 | INJE | pin9 |

| pin#15 | Green/white | 1 | INJA | pin7 |
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
| 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
| Fuel Pump/O² Power Control | ||||
| L-jet Pin | Wire Color | Use | number in setup | ECIII pin |
| pin#20 | Pink/black | looks to power S2 fuel pump/O² | STEP_A | small#4 |
Tachometer
| Tachometer | ||||
| L-jet Pin | Wire Color | Use | number in setup | ECIII18 pin |
| pin#1 | Yellow | coil also goes to cluster(tach?) | STEP_B | 17 |
