I had one of these long ago...back in the 90's when there were virtually no tuners for LT1s. Not really worth any HP gains IMO....there was a wire coming from the JET module that has to be spliced with a certain pink PCM wire I seem to recall....but you need the directions to find out which specific wire to splice. I don't remember as it was forever ago. Once installed mine never gave any check engine lights. You would be much better off to just get a mail order tune.

+1 on the mail order tune.
Remove PCM from under cowl (2-10 mm bolts)
Unhook the red blue white and gray pigtails
Remove the two 1/4" bolts holding the plastic cover to the PCM
Pack and ship to your tuner of choice
Takes 10 minutes. Much easier.
Tuners include madz28, pcmforless, Lt1pcmtuning.com aka Solomon. The choice is yours here. I can't speak for any of those vendors except madZ28, his turnaround was super quick and everything you can think of is essentially tunable, although I haven't run his tune yet in my car. Just search and find one you are comfortable with. Good luck.
