Strap? Is a regular wire the harness got to attach to a J nut with a screw to dashframe. The other end of the wire plugs straight to a VL bracket provision on rallye cluster and is on the multipin conector on standard clusters. On B bodies at least.
BE CAREFULL... if the VL is NOT grounded you can BURN the gauges. The VL requires - and + to work. If - is missed the points inside will keep closed allowing 12 volts to the gauges. The ground wire must be in place. The chassis ground to cluster is also good to be there and nice..
on pic the VL with the bracket provision for the ground plug. The wire gets a wider terminal ( prong is also wider ) to save from connect a diff wire there which is not the propper ground wire

Thanks for the replies. I am about to go to the garage and dig into it. I will report back .
I removed the wires to see the VL. The light blue wire coming from the VL makes a connection to two gauges . Do I have to add a jumper wire to have all three connected ? Thanks
Edit . A connection between the light blue /gray on the oil gauge and the empty dark blue/ post . On the gas gauge .

Yes. Normally the wire feeding between gauges and VL is black. Dunno wher it comes that one.

Yes the rectangle isolator piece is missing . What material could I use in its place ? What size nuts / thread go on the ammeter post ? I’m gonna retest the gauges and make sure they are good. Would the red wire touching the back of gauge cluster without the isolator cause a short or potential melt down ? Thanks . Yes you need to isolate the studs on the ammeter, otherwise it's meltdown/fire time, you could use some electrical insulated fiber washers, they need to be under the nuts that will tighten the ammeter studs to the housing, I'd recommend you buy/purchase a test meter, not a test light, to check for continuity/ground after you install the insulated washers under the ammeter retaining nuts, then ground one lead of the test meter to the cluster main housing and test each of the ammeter studs with the other lead while maintaining ground with the first/black lead of the meter, make sure the meter is on continuity/Omega, depending on the type of meter you have: digital or analog, it may also have an audible sound/buzz for ground/continuity, needle movement or digital display? whatever it is, you DON'T want any ground or continuity when probing the ammeter studs individually while maintaining ground with the black lead on the main cluster, if you have ground/continuity then either you didn't properly isolate the studs, the gauge may be defective, or a host of other maladies we can guess at all day, you really need a good meter to help you find/solve issues.... FYI: depending on your meter the only continuity you want to see on the ammeter studs is when you apply both test probes to each stud at the same time....AFTER you've confirmed each stud is isolated from the cluster housing/chassis ground As far as the oil gauge function, make sure you have the correct sending unit it should look like this....
