I'm rewiring my 82 Camaro with crossfire injection to use the 7747, =
which seems to be fairly straight forward except for a few variations =
between different pinout charts.
1)One chart shows 4 pins for the injectors D15 & D16 for injector A and =
D14 & C15 for injector B. The other shows just 2 pins with D16 for A and =
D14 for B. The stock Camaro harness/computer only used 2 pins. The wire =
colors match the 2 pin chart(D16/D14), but also match 2 of the 4 pins on =
the other chart, but not the same 2(C15/D16). What are the extra 2 =
wires? Do I need them or can I just run it the way it is? Why the heck =
is the light green wire D14 on one and C15 on another?
2)In the archives it says A3 is canister purge, but neither of GMs =
charts show this and just list A3 as not used.
3)A4 is listed as EGR and EVRV control. What is EVRV, and does this =
control both or is it either or?
4)A7 is either TCC or MT shift light. Since I went from AT to MT I would =
like to rewire this to the shift light, but is there a way to set the =
rpm for the shift light?
