So I got my DIY wideband o2 built. 2A0 Rev 4. But now im confused what what i hook up to V1-V3 and T1-T3. And where i hook up RPM(primary on the main coil or go off the ECU?) It's a turbo del sol btw. I have a palm pilot and i bould a null modem adaptor. is that the thing i needed? Also a male-male gender adaptor. How do you guys have your set up? What cables did you buy and where did you run your wires? I just can't follow their website any longer, it's like an epileptic monkey and there's ---- all over the place. I basically want tune A/F with it's respective RPM and boost level and data log it. Any help is good help to me. Thank you.

Edit: Sorry, about the cross post, i don't know how to delete it.
