Can You Identify This Plug?
This is a 68 Firebird Sprint restomod. New OEM style wiring harness plus a few accessories added. Trying to sort out an electrical gremlin and found this plug exiting the stock steering column. The column has a cruise control stalk but no other components. Could this be for the cruise control? I have a TSM but find the wiring diagrams lacking.

A 68 factory cruise control stalk only has three wires. Black, Blue and Tan. You have what looks to be an aftermarket (Rostra/Dakota Digital?) plug. Rostra schematic shown.

Thanks OG. That might be it. Never heard of Rostra but just looked them up.
And Turbo69 - frame off resto with a Global West front and rear suspension, Clifford intake with 3 Webbers, TH200 trans. Looks completely stock until you open the hood. |

4 pin Molex connector, check with the column manufacturer or cruise control manufacturer to see what they intended it to be plugged into.

It plugs into a second harness from the cruise control box. Usually located under the hood. But since you have Webers I doubt it's still there.
