Here are the OEM wire colours as they match up to the LS2 connector oriented as shown previously. You can trace the wires in the STH to see if they mate the proper pins up with these wires in the OEM harness.
black/yellow/brown
purple/blue/green
the black/w and grey OEM wires are not used for the LS2

I sent the tb and the harness to Speartech for testing so I can't trace wires and colors for a while.
I'm wondering if tsystem with the old style tb using the two plug system was ever physically tested with the 90mm tb and his harness or if the wiring blueprint was used to devise the harness and was seen to work in theory but never physically tested with the old style harness and plugs.
I'm going to ask John if he can hook up the 90mm tb I sent him to the 2 plug harness and see if it works.
Have to wait and see what he discovers.

Good news! Got an email from John Spears last night. He put that tb on one of his engines and it is defective!! I'll be ordering one up first thing! Maybe this saga has an ending in sight!
The REALLY good news is that it was not somehow my screw up. I know so dammed little about this new technology that when something that is supposed to work doesn't work this little germ of doubt about my part in it can't help but start growing in the back of my head. Thanks to those who were encouraging throughout this mess. I needed that.
I'll post up when it's up and running and now maybe we can get on with the headers, heads, cam, meth, and of course the ever popular and not to be forgotten mjhoward heat exchanger install.
Zippy.... I was beginning to think maybe I wasn't going to be able to make our date 3 weeks from now. Looks like we're back on schedule!
Later Jim

Finished mine up today. Looks like my harness was OK. Tried switching those 2 wires(C & E) to see what would happen. It was just as you described. Pretty well same codes. Takes 15 sec or so for REP mode to clear on its own. I did get a code P2101. Turned out the throttle plate was sticking when in the fully closed position. Had to loosen and retighten it. It's a very tight fit. Time for some tuning when the roads dry up around here. Nice coat of ice today. Idles really smooth and seems to respond well to accelerator pedal position.

So I'm driving up on the 29th or 30th to see them. Zippy hasn't said that I can or can't help. Hope they'll let me in on the action. I don't want to just hire it all done but I do need help.

When you changed the wires did it run right but then throw the codes when you tried to restart?
I ordered another tb from WCCH and it's supposed to be shipped overnight on Monday so I should be up and running Tues night or Wed. I won't believe it's fixed until it's running so I'm still nervous.
FYI: John Spears told me in no uncertain terms that they physically test every item they sell before it gets shipped out.

I can do the "wrenching" but getting it to run and run right is so much different than it was in 1962 that I'm better off getting help in case something goes wrong... like in the case of this tb with me being out here in the boondocks with no help available.
