89 Corvette Engine Wiring

Hi All,
I've come across a Corvette engine ('89 350 I think) with Tuned Port
Injection. Actually the vette's totalled and I'd like to keep the engine
with TPI. what will I need to make the TPI & ignition work? I can get the
computer but no harness.
I confess ignorance about all the sensors. I can't have the transmission.
Speed sensors? DRAC? Instrument cluster inputs?
I'd really appreciate any advice to put the engine on the track again.
Best Regards,
Jim

The safest thing would be to take the ECM box even if you have to
leave the harnesses.

That's cool enough and I already ensured that "I can take all the pieces
parts to make it work" and the ECM's included. I just need to make sure
that there's not something that the new chassis can't support.
If I have the ECM, aftermarket engine harness and all the IN-ENGINE
sensors, will the engine be fully contained for TPI and ignition? There's
no other speed sensor or necessary input from elsewhere in the vehicle like
speedometer, gauges, transmission, etc?
I'm gonna put this engine in a basically empty chassis with a manual
transmission. So, there's no other inputs or systems whatsoever to support
any drivetrain function besides the foot pedals.
Thanks for the reply.

Jim

I think that the ZF 6 speed has 1 or 2 plugs on it (1-to-4 sensor and
the VSS) which will may not be supported by the ECM if the other car
had an automatic.

Hmm. The donor Vette had a 700R automatic transmission. It has a 1"x1"
square, 4-pin connector on it looking down from the top of the transmission.
I don't think that transmission's electronically controlled but am not sure
what the connector's for (speedometer?). Anyway, does this indicate the ECM
needs input from the transmission or wherever that connector goes?

The plug that you describe is probably the same 4 pin plug on a ZF-6
as it is on the auto. The electrical manual for my 1990 shows this 4
pin plug & the manual does NOT differentiate between auto vs. manual
(2 pins go the the ECM and the other 2 go to the selective ride
control module, so it has to be the same plug). I have seen a ZF-6 out
of the car and this plug is about 1x1 square on the forward left side
of the ZF-6 trans. ALSO on the ZF-6 is a two pin plug for the
one-to-four which connects to the instrument cluster & ECM and which
you DON'T need (and everyone routinely disconnects this plug anyway).
Hope this helps.

Shut-up Dan. Go buy a factory service manual and stop living off your
friend's ZR-1.
