Rally Pack Wiring

What is the pin configuration for the '70-'72 Rally Pack gauges? I’ve traced some of them but I’m unsure of my results and there are several wires I couldn’t track down. Here’s what I think I know, help me fill in the blanks:

1-Grey ??
2-Empty
3-Tan (Fuel Gauge)
4-Blue/White (Oil Pressure)
5-Tan/White (Brake Light)
6-Pink (12v Power)
KEY
7-Brown ??
8-Green (Temp Gauge)

Connector terminals

Thanks for the quick info. Is it possible to buy new crimp terminals to replace the round connectors? Mine look pretty bad, might be a good idea to replace them and solder them for better connections.

hey i was going through your thread im in the final steps of my wiring. but unfortunetly the guy who was fixing it stiffed me and i ended up loosing my original harness to him. i bought an after market one and it is all wired up with the exception of the guages. as you can imagine it is no longer color correct so we dont know where to plug in the wires on the rally guages. i was wondering if you ever figured out what wires 1 and 7 went to

1-Grey ??
2-Empty
3-Tan Fuel Gauge
4-Blue/White Oil Pressure
5-Tan/White Brake Light
6-Pink 12v Power
KEY
7-Brown ??
8-Green Temp Gauge

Refer to this thread for detailed instructions

https://classicoldsmobile.com/forums...-question.html

and refer to this diagram as to the new positions of these wires to convert to the Rallye Pack from Idiot Lights



As to answer your question the Grey wire feeds the lamps and the Brown wire fed the Gen Warning Light but goes back to the ignition switch on the ACC side. Hope this helps Wiring can be a pain at times.

Can anyone recommend a company to purchase a new Dash Wiring set up for my 72 Cutlass with Rally Pack Gauges / Auto. Transmission? I was also looking for something that will handle a newer style radio system.

Thanks, Pat

rallye pac for my 72 442

Hi
i had a reg 72 S years back. the fuel gauge had a dummy light for the GEN and the HEAT.
Now I have purchased a rebuilt 72 442.
what is the correct factory Rally Pac for my car:
a) the 2 pod on the dash where 1 is the fuel\engine tmp\oil pressure (no #'s just lines) and the 2nd is the toc\tach (clock with tach around edges)
OR
b) the 3 pod unit (oil pressure\ engine temp\battery) that went on the bottom the the dash between the steering wheel & radio?

It depends on what was checked off on the options sheet when ordered, as to if it had the Rally Pack or "idiot" lights. Even on the W30's it was an option and not standard. The three pod unit is an aftermarket add on and not factory original.

One thing to remember when doing a conversion from idiot lights to gauges is to disconnect the TEMP check circuit. If it is not disconnected, every time you start your car, the temp gauge will peg to the max side, and then drop off and act as it should. You don't want your temp needle to do that - it could work loose or just stop working after awhile.


With idiot lights, when you start the car, the TEMP light comes when you put hour ignition key in the RUN position, and then go off after the car starts. When converting to gauges without disconnecting that TEMP check circuit, it's that same check circuit action that pins the temp gauge needle.


The temp check circuit can be disconnected by simply backing out the green wire from your ignition harness, down on the steering column where the ignition harness connects into the under-dash harness, and then taping it off.

Pat, Google M&H Electric Fabrications, Inc. They make all type's of Factory correct harness, and they go by GM Spec's, Use factory correct colors for the wires and correct connectors! I have used there services, and Highly Recommend them!

New to this forum," this is critical information for the life of your gauges, it sounds like to me." I read somewhere , somebody said to pull the Lt green wire at the guage connector rather than under the dash at the steering column within the ignition plug. Does it really matter where this wire in disabled?? Thanks,Jim

This info helped tremendously! I went ahead and added LED lighting and now I can see the gauges at night. I restored the radio as well and changed the backlighting inside to LED to match the gauges. I added a bluetooth receiver inside and I play spotify and sirius over my radio because there really isn't anything left to listen too on AM or Fm these days. Here's a link:
Thanks for the great info!

Nice job. Where did you get the LED bulbs? Do you have the part numbers for the LED bulbs?

Thanks! I bought the led lights off eBay. Do a search there are tons of listings. For the radio I just modified a 194 led bulb and hardwired it to 12V switched on inside the radio. These LEDS will last about 10000 hours and they only draw maybe 5 milliamps of current compared to .5A for incandescents. I used these ones but you might be able to get em cheaper.

Dakota Digital VHX Gauges

Here are the pictures I promised. I took some with the illumination off and some illuminated. I think they look pretty good. These are the "alloy face" versions. Good instruction sheet, good support from Dakota Digital and your post made it pretty easy!

Asd you can see, the install was easier than uploading the photos! They were right-side-up when I started!
