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.
