I put a GM TBI on my Ford I6.  I had to convert the dist over to electronic
pickup, but that was no big deal.  You need a standard reluctor / magnet
setup.  If Toyota ever made such a thing, that would be the ticket.
Otherwise, you will have to adapt.  

You obviously have a vacuum advance setup, so simply disconnect the vacuum
hose, which will keep the distributor plate in place.  Then, connect the two
wires from the reluctor to the P and N connections on the GM module.  If you
hook them up wrong it will still run, but when you remove the tan/black
connector for timing, it wont run if they are hooked up wrong.

I would simply go and buy a newer TPS sensor, with the new round connector.

Cheers,
Tracy

Hi all, 

I accidently posted this in the DIY EFI list yesterday, I meant to post it
here, so here it is today, with a few points I left out yesterday.


First time poster here.  I'm trying to put TBI on a Toyota inline 6 engine,
and 
I have acquired some parts already I have a 1227747 the original harness
from a 
Chevy k1500, a Throttle body(4.3), and tons of reading material. I'm
constructing an interface, and have the software to log and make edit bins,
and access to a burner.  I just noticed that
the TPS  on the Throttle body I have is of the older type plug(looks like
the MAP
sensor plug), and the harness has the newer roundish plug.  Is my best
course of
action here to buy a newer sensor(will it fit?), or to find a pigtail and
solder it onto the harness?
I'd also like to ask how to understand the bin listings you have on the FTP
site.
I don't quite understand what listings are for what engines, and what
options.  

If anyone has any information on how to interface the distributor(points)
off my I-6 engine
to the ECM, I'd love to read that as well.  That's the area I am weakest in
my understanding.
I don't see how the GM distributors actually change the position of the
rotor to
change the timing.  I suppose they could NOT change the position and just
let the
spark jump, but that seems wasteful.  I don't understand what the 4 wires
leading
from the distributor actually tell the ECM. (When to fire and when to inject
is
obvious, but that would seem only like 2 wires.)   Trying to understand what
all
is going on.  


Thanks
Dave

P.S.  Thanks to all the responses from the DIY list.
