2nd try about injection...

[TMatthe at aol.com]

Anybody have the schematic for the GM 3 wire sensor? I have headers on my 84
Monte Carlo and I'm having trouble with the sensor cooling off and I want to
wire in a heated sensor. Plus, can someone explain the different types of
sequential injection? I've heard that there are a few different types
(phased? and true?) I understand sequential inj. is fired in firing order,
and I'd like to set up a sequential injection on my 69 455 Firebird, but
since I have no experience in sequential inj , I would like to use the
minimum amount of extra sensors specific to sequential injection. Any
suggestions/comments/ stories on how someone else put sequential injection on
a old dinosaur?
TIA,
Tom
