Conversion to Rallye Dash

First of all... the instructions say to pull the bezel out of the dash and tilt it to access the connectors. There isn't any strength to the contact pins on the circuit boards and these 3 are too close to the top too. Pins are often bent/loosened/pulled out of this board. what to do?
Use a connector like this... https://www.grainger.com/product/HOPKINS-TOWING-SOLUTIONS-T-Connector-440A89
Solder or by other means connect wires from male terminal side onto the circuit board. Wires from female terminals will attach to cars harness wires.
The extra white wire in this connector can be a added chassis ground wire for entire inst' housing. A ring terminal under a screw helps anchor this harness to the instrument panel. OEM contact pins on the small circuit board are no longer a worry.
