Default 1991 4.3 TBI Timing Set Bypass Connector Location

So I used to be a member of this club quite a long time ago. (Just can't remember the login info). I've attached pics of my old truck (Sold back in 2014). I remember some of the moderators, maybe they will remember me as well. At any rate, my son has a 1991 S10 Blazer. I did alot of work to it and now want to set the timing as the distributor has been moved. On my old Blazer, the connector to be unplugged was underneath the passenger dash. I for the life of me cannot locate this connector under there and was wondering if this 1991 has a different location??? It's quite frustration as I need my garage, and have spent the last few hours combing the truck for this plug... ANY help is appreciated.

My old 89. bored .060 over, Chevy 350 flat top pistons, mild comp cam, msd ignition, edelbrock HR intake, venom injectors... So much to list! lol I miss it.

So, I believe I found it. Tightly bound to a large bundle of wires closer to the left side of passenger footwell. Albeit faded color, I am pretty sure this is it....
