Anyone know the signal input of the 85 Monte Carlo SS dash gauges? Need the fuel level, oil pressure, & coolant temp.. Will buy senders once I know the signal input required (ohms). Thanks

Gas gauge is 0-90 ohms, I think. You need stock 85 SS senders for oil pressure and water temp.

Thanks for the input. Are you sure about needing the stock senders? I've seen Monte's w/computers deleted that looked like they had after market coolant temp & oil pressure gauge senders. Mine is a 350 swap w/ computer delete. I should have mentioned the computer (PCM) delete in my question.
Do you know what the stock sender's output is?

If you mean the factory Monte computer, it has nothing too do with making your gauges work. No matter what engine you put in the car, or what brand for that matter, you need to use the stock senders to make sure the gauges are working correctly. I have an LS1 in my car, but am using 84 Monte Carlo gauge senders for the oil and temp.
