EL gauges and inverter control circuit Help

Click For Summary
SUMMARY

The discussion focuses on integrating a Chrysler 300M electroluminescent (EL) gauge set into a 2000 Intrepid. The user must swap the gauge faces onto the original cluster electrics due to compatibility issues with the onboard chip. The primary challenge involves connecting the 6-pin inverter from the 300M board, specifically identifying the correct power connections for the four unknown pins, which are essential for proper functionality of the EL gauges.

PREREQUISITES
  • Understanding of automotive electrical systems
  • Familiarity with electroluminescent gauge technology
  • Basic knowledge of circuit board components and pin configurations
  • Experience with vehicle dashboard modifications
NEXT STEPS
  • Research Chrysler 300M EL gauge wiring diagrams
  • Learn about inverter circuits in automotive applications
  • Investigate the Intrepid's stock dashboard circuit board layout
  • Explore troubleshooting techniques for automotive electrical issues
USEFUL FOR

Automotive enthusiasts, electrical engineers, and DIYers looking to modify or upgrade vehicle dashboard systems, particularly those working with Chrysler vehicles.

Hi all,
Just joined and have a question I'm hoping someone can help me with. I'm putting a Chrysler 300 M electroluminescent gauge set in my 2000 Intrepid (backlit gauges). The problem is that I have to swap the faces onto the original cluster electrics in order for everything to work properly. I can swap the complete 300m cluster into the Intrepid, but then there are all manners of warning lights illuminated as the on board chip is progrsammed differently than the Intrepid. It's pretty much a straight plug in swap to change the faces, except the Intrepid cluster does not support the inverter for the EL gauges. The inverter off the 300m board has 6 pins and I'm having a little trouble figuring out what power to run to each pin. 2 are easy as they are the output to the gauge faces. I'm assuming the other 4 are power and a reference circuit from the vehicles dimmer for the dash lights.

Here is a pic of the circuit board:

The boxed dashed line is the inverter circuit where the inverter resides on the board.
The output lines are the two circuits that come out on the left and are labeled "output" on the print.
I need to identify the other four inputs to see if I can source the power and control from the stock intrepid circuit board.
I have higher resolution pics, send me your email address if you would like to see them. Be warned though, each pic is 5 megs!

Thanks for any help you can offer.

Cheers

BJ
