Please help! I'm so close! I found one wire I missed. The red one that runs from the ignition switch to the main 12v source, just before the 20a fuse (as shown on the wiring diagram from DIY). Do I use a switched 12v source like I did for the other yellow wire coming from the ingnition switch? Doesn't seem right to me! The fuel pump relay is wired like this:
85 to the purple wire from pin 37 on the ms II.
86 split to 86 on the main relay and to the switched 12v source ( I used the spare in the factory fuse box)
87 to gray (I think it used to be beige)from the fuel pump and shared with the red wire from the LC-1-power
30 connects to 30 on the main relay, then thru the 20a fuse to the main power to battery
The fuel pump runs for a few seconds when the ignition switch is turned on, as before. I am wiring in my own relays (the stock fuel pump relay was all gummed up) and have added one for electric fan control with overide switch and it works fine using the FIDLE circuit.
One last thing: the box for Calibrate AFR doesn't appear anymore in TunerStudio when I click on it?
By the way, thanks to all those who have replied to my posts! You have been a great help, and I have learned a lot!

Re: It Idles! But no Wideband Power for Calibration
I made some progress. The 12v switched supply only give power for about 5 seconds to prime the fuel pump. I used an alternate source to supply power during calibration of the LC-1 and it worked. What puzzles me is how things are working without the one red wire from the ignition?
