- 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 | |
| pin#30 | White/red | |
| pin#14 | Light-blue/red | |
| pin#32 | Yellow/black | |
| pin#33 | Orange/white | |
| pin#15 | Green/white |
| TPS switch (need to get a motronic pot type) | ||
| L-jet Pin | Wire Color | Use |
| pin#18 | Purple | common |
| pin#3 | Yellow | WOT |
| pin#2 | White | idle |
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 |
| pin#34 | Orange | will be the IAC control |
it looks like l-jet pin#28 Yellow/red need to go to ground to enable the S2 double relay
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 |
| pin#20 | Pink/black | looks to power S2 fuel pump/O² |
| Tachometer | ||
| pin#1 | Yellow | coil also goes to cluster(tach?) |
Power
| Power | ||
| L-jet Pin | Wire Color | Use |
| pin#20 | Red | power shaired with injectors from S2 |
| pin#10 | Red/black | power direct from S2 |
| Grounds | ||
| L-jet Pin | Wire Color | Use |
| pin#22 | Black | ground to CLT and thermostat case |
| pin#16,pin#17,pin#35 | Black | power grounds |
