zomeizter Posted September 1, 2023 Share Posted September 1, 2023 Any tachometer swap gurus know how to get the blue instrument cluster tach to read correctly? I swapped in a full gauge cluster into the MJ but I assume it came from a 4banger because I'm at 2000-2100 RPM at idle. I took the tach off the housing hoping there was a potentiometer to adjust but no dice, do I need a 6 cylinder tach circuit board for this to work? I see a couple of ICs soldered on the tach CB, maybe one of those needs swapped? Holler... Link to comment Share on other sites More sharing options...

zomeizter Posted September 10, 2023 Author Share Posted September 10, 2023 I went ahead and ordered a tach signal converter and will install it soon, I'll holler with the results... Link to comment Share on other sites More sharing options...
zomeizter Posted September 10, 2023 Author Share Posted September 10, 2023 Solved. The installation of the universal tachometer signal converter fixed the RPM display error, tachometer is all good now... Link to comment Share on other sites More sharing options...
