Does anybody have this? I am doing an lt1 swap and I am down to the wiring at this point. My 130$ service manual doesn't have it.

 

I couldn't find it either when I did my engine swap. I put a multi-meter to wire and this is what I figured out (or didn't figure out). 1989 Firebird 2.8L, T5 trans.

A.... BRN.... unknown
B.... PNK/BLK.... 12V power from INJ fuse
C.... BRN/WHT.... MIL lamp (ground this wire to turn on the light in dash)
D.... BRN.... 12V power from FAN fuse
E.... WHT/BLK.... unknown
F.... PNK/BLK.... 12V power from ENG-IGN fuse
G.... PNK/BLK.... 12V power from GAGES fuse
H.... TAN/BLK.... unknown
J.... ORG.... Datalink
K.... BRN.... VSS buffer box speed input
L.... BLU.... VATS
M.... BLK/WHT.... VSS buffer ground
N.... unused
P.... unused
R.... PPL/WHT.... 12V from CRANK fuse

 

Hey thank you so much. This helps a bunch

 

You can verify with wire continuity checks. Just make sure battery is disconnected from battery. Put key switch in proper position depending what you're testing.

 

This is what I've got; Can't claim it's 100% - but should be close ! ( see notes for induction specific details. )

 

Thank you!
