Gauge Pack Swap

[85Supreme]

i bought a whole interior to swap into my cutty for the buckets and color change, i also got a rally gauge pack with the car because the interior was out of a salon. im planning on swapping the rally pack for the gandma speedo setup. just wondering what i would need, to make it work, or if it plugs right in but i doubt that, any help is appreciated, thanks for looking

I just completed this swap. On my Diesel. Installed a Diesel Rallye Pac. Follow the wiring diagram in the link Blake give you. Some advise I have. Get a steel brush, and clean very exposed copper on the panel. This thing is super senstive to resistance. Dont forgot to take the 5 nuts on the back and clean there too. My guages didnt work till I cleaned there. Also I would highly suggest adding a ground ( I just cut some plastic to expose the copper bolted the terminal to the pac) using the extra ground wire you will have anywayz. And use the brush to clean the terminals on Connector 2 and get a mini-screwdriver and bend the tab up alittle to get a good contact with the PC board.

Also I but a connector in terminal 8 cuz I wanted an Oil Light. I ran a wire from terminal 8 to my Oil pressure switch.
