should’ve taken pictures but now dash is back on

Noticed a module to the right of the hvac unit (hanging off the hvac unit) with a chip connector but nothing to plug into it. Black box with looked official GM rather than aftermarket. Any ideas what this might be?

tried searching and might be a cruise control piece? But seems an odd and no connector but my cruise worked fine?

car is a 91 TA 5speed

Any steers would be great

What you describe sure sounds like the cruise control module, and my only idea as to why it isn't plugged in, but your cruise control works, is this;

Perhaps sometime in the car's past the cruise module failed, and someone plugged in a new module and tucked it up into the dash somewhere, without putting it in the proper location?

Thanks

Yes possible it’s had some ‘customisation’ in the past

And you are NOT talking about one of these, right?

Yep none of the above. This is attached to the hvac box behind the dash. It’s about where the ECU sits but slight to the left and behind it

black box with a single chip in it (quite loosely enclosed, rattled about a bit)

Also to add not the VATS module which is attached to the dashboard

Maybe it was put there by the government. Have you been speaking ill of parliament?

Lol, with Boris as PM they’d have to track most of the nation

I think OrangeBird is right and it’s the Cruise Module perhaps repositioned on later airbag cars. I have a pro-flo intake and no immediate provision for the cruise cable so no loss if so

For closure, looks like it is the cruise module per post 6 of the linked

Related question. I'm building a 1990 with an LS1 so not a big deal (I can't use this module, right?) ... But my car does NOT have a cruise control stalk on it. I was surprised to find this cruise module in the passenger side dash because of that. Did all cars get it? or was my stalk perhaps swapped or something? Thoughts?

Do you still have your vehicle SPID label? If so, look for code K34, Electronic Cruise Control.

This label seems to be long gone, sadly.
