87-91 tbi suburban wiring diagrams

Does anyone have good wiring and complete wiring diagrams for the 87-91 suburban/blazer? I did an ls swap on my 91 and think i lost my speedo signal in the process. Biggest indicator is the fact cut the twisted purple/green from the original harness and spliced it into the ls stand-alone harness, so i don't know if the factory gauge panel needs any other inputs or tagged into the stand-alone harness for the ecu to tell it what's going on
