jay i like your thread.

but one question.
how you get it to start
did everything from the s12 work with the main harness?? what do i need to do to get it starting right??
was it hard to get it started?
fuel pump. how do i wire it up wo get it working with the motors ecu?
I never hooked it up to the ecu
I just grounded the white wire up directly below the green/black (power from efi relay) wire. And didn't bother with a relay. Fuel pump just runs at all times that the run is on.
ALSO, My starter did not want to crank at first, until I found that it's not addressed in the wiring guide. It's a yellow blacl wire on the passenger side harness, and a yellow black wire on the KA harness. connect those and BOOM! crank action!
This thread answered all the rest for me
ClickyAfter checking the wiring, no joke, 12 times. I cranked her and she started in 3 cranks. Nearly instantaneosly. All in all, This swap was MUCH easier than I was making it in my mind.
As for the dash, The coolant temp sensor is the same between all of the engines. So that as fine, And the CA20 Oil pressure sending unit goes into the KA block just fine. just wire that up. Voltometer works fine as is, as does the fuel guage. The Tach is an issue with our cars and the KAde's, because they have a 5 volt system, instead of 12 (on some), so mine doesnt work until I figure that one out later. and the Speedo? Just use the gear from your B trans in it. They have the same gear between the two and will have no issues.
