I needed to remove the Instrument Panel in order to check two things: lamps (I thought one might be out behind the speedo, since it’s hard to see in the daytime – both worked, so I guess I have an issue with the light sensor or dimmer…), and the tach fix.

I made this harder because I didn’t take the “white” housing off behind the gauges.


Originally, I just removed the circuit board from the backside. Because of that I couldn’t really tell how the speedo LCD was attached. Once I removed the housing, I could get at that reddish-brown connector on the LCD panel itself (yes, you can see it from the top too). So, don’t try to remove the white connector on the circuit board.

You can see the connector here (and also in Paul’s image above)


How come I see other circuit boards with nice component markings on them? Mine has nothing.

For others doing this, removing the circuit board from the back means you have to remove the pins from the analog gauges which push into the circuit board by pulling/prying the circuit board off. The pins will pull out of their sockets, but they take a little prying and do it evenly as Paul’s directions indicate

I need to get a potentiometer tomorrow and hook it up. Now, I sure hope I didn’t mess something up on the LCD or the circuit board when I was prying on it


I would love to see the schematic of the board. When I cut off the resistor (pins 4 and 10), why not put the pot for testing (and the ultimate resistor load) there, as opposed to across C4? No, nevermind, don’t tell me – I have enough to do and if this works, that’s great
