24v Instrument Cluster compatibility (1 Viewer)

[CRZR45]

I have a 1986 Bj 73 3b 24v with basic dash cluster. I have 2 used clusters and can’t get gauges to work when plugged in. I know I need to add tac wiring but oil,temp etc are different wiring ? Does anyone have a cut pigtail I can graft to my harness or is there a simpler way? Here are pics of my cluster and the 2 spares I have

Do you have pics of the plugs and sockets you are trying to connect?

I have to get the dash part to look at the vehicle ones( I tried this mod a few years ago so all I remember is only one or 2 gauges worked when plugged in) just was going thru parts and want to swap in one of these since I have them. Here are pics of my 2 cluster plug holes (ones with tac)

I never checked for this specifically but can you order the terminals brand new that plug into those clusters still? I imagine they would come from Yazaki if still available. Seems like that will be the easiest way to route the wires from the firewall where they need to go for the cluster you plan to use.

The way those plugs/contacts work is pretty eccentric.
Finding them in a wreckers yard would be ideal, but not possible in USA.
