[Gmecm] schematics for 02 bonneville and ECM to use

[jayjunk at laserpubs]

Hi Bob, Brian
Great ideas, thanks.

I wasn't clear-
When I swapped the Buick motor & trans in, I took the ECU and harnesses 
from the donor car. (87 Olds Delta 88) I simplified/reworked the 
harnesses, and used the donor ECU.

Now I have the Bonneville motor and trans, the ECU itself, and the 
harness tying them together.

So, it will be similar to the previous project, except maybe easier.
The '87 was a beast because there were about three harnesses connecting 
the engine, the ECU, and everything else.
On the Bonneville, the ECU connects up to the engine pretty directly, 
and there's just one or two connectors tying that harness to the rest of 
the car. I shouldn't have to hack the engine harness at all.

But, I'll need the schematics so I can interface from those connectors 
to the rest of the car and/or support systems.

So, I'll check out Mitchell on Demand and Alldata.
And those other sites-thanks!

I have some photos on my site
www.laserpubs.com.personal

and I posted some videos on  YouTube from 2009 when I was just getting 
the car running with the Buick motor in it.

Yeah it's ugly and rough.
At that point I probably didn't have $1200 in the whole car!

cheers
Jay
