RallyE instrument cluster wiring diagrams

[Vvellajr]

Hello all, very new to this forum. I have a '73 Challenger with rallye instrument cluster. I need the wiring diagram for the cluster. Ive managed to download 1/2 of the diagram, specifically page 8-94 ELECTRICAL - WIRING DIAGRAMS but cannot find the corresponding page (perhaps page 8-95 or 8-93.  Im trying to figure out where exactly the TACH wiring goes and where it connects in the engine bay. Any help would be appreciated.

Welcome to the site. @Vvellajr

While not specifically 73 this page has 70 rallye cluster wiring diagram color coded. Tach wiring should be the same.
T11-18GY*  on the diagram. Neg post on coil to bulkhead connector(s) to the tach.

The first thing anyone who wants to work on their car is to download a complete factory service manual. All of the diagrams are there.
Here is the link. The info you wanted is in the Chassis manual but you should also download the body manual as well.
