You're in luck! I got a TPI engine from an '89 Firebird and I bought three manuals to go with them and
they happen to go back to '82.
This information is from the Haynes, my good set of diagrams is at the office where I am drawing the
schematic for the tuned port.
Dimmer switch - looks like 4 pos connector with only 3 used
yel - from headlight switch feed
tan - low beam
lt grn - high beam
Flashers, turn signals, horn and key in common 11 pos connector with 10 pos used.
blk white from collumn not used
Horn
blk - horn relay
Turn signal
ppl - from signal flasher
brn - from hazard flasher
dk blu - right turn signal
lt blu - left turn signal
dk grn - unused?
yel - unused?
Key in ignition
tan - door jam sw
lt grn - buzzer
Ignition
yel - start sol
ppl - ign 1
brn - acc
red - bat 2
red - bat 3
brn/wht - ign 3
org - ign 3 (same as above)
dk grn - grd 1
tan/ wht - grd 2
Connections
Start grd 1, grd2, grounded
ign 1, bat 1, sol connected
Run ign 1, bat 1, acc, bat 2, bat 3, ign 3 connected
Acc acc, bat 2 connected
Note: bat 1, bat 2, bat 3 common
I'm a degreed electrical engineer, and I still didn't see where the turn signal interupts the stop light
circuit in the diagram. It was a little hard to follow at times the way it's layed out. I wish I'd had the
better book here.
Whew, this was a lot of work on my part to provide this so in turn I expect you to let us know how it
worked out. I'm thinking of doing the same thing.
