This is a link ot my documentation for wiring all accessories up(such as cc and the ECU and the starter interlock) I didn't write everything down that is required for the swap, but it sounds like everything was covered. Also, when you get the tranny, remember to get that center axles (that goes to the right CV axle) these ARE different in all formats (GT, auto/ man, and GL auto/ man; basically there are 4 different axles here)
Actually, I just looked at my page, and only the starter interlock is described. This will give you whjat to do to start and use the car, but the cc and ECU will be short 2 inputs. Basically, the cc won't kick out when the clutch is pressed in, and the ECU has a special circuit that tells the ECU when the clutch was pressed, or the tranny dropped in neutral, to allow the ECU to prepare for the idle mapping so the car won't stall. I will update and create the pages to describe these circuits.
As for the swap, it is basically a pull-out put in affair. If you're good, you could probably have the car running in a weekend. If you also plan to upgrade to the GT tranny, the shift linkages are again different, get that off the GT, and ALL axles are different, as well as the brake spindles. You can use your GL brake rotors and calipers, however. Remember to get the flywheel for the proper tranny. GL trannies use a 7 or 8 inch clutch disc(I forget what size), and GT's use a 9-9.5" clutch disc, and will bump the starter out just enough to accomodate.
