Im not sure which wires are which on the passenger side kick panel connectors. I think the v8's diagrams are different and just need to know which the ground, VSS wire and serial data wire is to splice into the new computer and i'll have the wiring officially "Complete"

Unfortunately you can't simply splice in the VSS. The 3rd and 4th gen systems are completely different. Check out the write-up on Jag's that run about the different VSS's that were used in GM vehicles. If you are lucky, you can just get the Dakota Digital speedo calibration module and in essence plug it right in. If not, you'll have to get creative. Since I had a TBI computer, my VSS was totally different and there was no way to use the DD box. What we ended up doing was get the speed sensor out of I believe a newer S-10 or full size truck, mounting a 17 tooth sprocket on the yoke, and mounting the sensor off the exhaust hanger coming off the tail shaft of the transmission. In doing so, I was able to simply plug right into my computer, made it easy and it works like a charm. I've got my dad taking some pictures of what we did, and I'll include a full write-up on the swap guide about it after I finish some school projects in the next 2 weeks.
*Of course this doesn't matter with a V6/TPI car or if you are swapping the T-56/4L60E*

If you are keeping the T-5 like I did, it does matter if you have a TBI car. This has been posted before but I'll post it again:
1. The two-pulse (2000 pulses per mile) square wave (D.C current or direct current) used on all TBI
engines thru 1992, all computer-controlled-carbureted engines, and on 1985-1989 TPI engines.
2. A four-pulse (4000 pulses per mile) sine-wave (A.C. current or alternating current) signal is
required by the 1990-1993 TPI, 1992-1993 LT1 engines, and 1990-1993 Camaro 3.1/3.4 V6
engines.
3. A 40 pulse per driveshaft revolution speed sensor used on 1993 and newer trucks with automatic
transmission, 1994 and newer rear drive cars with the automatic transmission
4. A 17 tooth per driveshaft revolution speed sensor used on 1993-1997 LT1 engines with the Borg-
Warner 6-speed transmission. An 11 tooth reluctor ring is used on 1993 LT1 engines with the
Borg-Warner wide ratio (3.35 First gear) 6-speed transmission.
The TBI signal is completely different from the rest of the sensor signals. Hence why you cannot simply plug a Dakota Digital box into it or something. With the TPI and V6 sensors, you can use the box and just step up the signal.

hey TexasLT1, do you know where the VSS is on a 89 TBI car, since the speedo is cable driven, is it on the back of the cluster?
would I just have to swap it to a TPI one to get the right signal for a 93 LT1?

When using the LT1 with the T56 or 4L60E it doesnt matter if the car is a V6 or V8, tbi or multiport in 90-92
