Hooking up Tach
Hey guys,
I have never posted anything here but I am having trouble figuring this out.
I bought an 88 Firebird Formula not to long ago with a LQ4 swap. I am trying to figure out how to hook up the tach. All of the other gauges are hooked up and work properly.
It is the digital gauges. From what I understand you have to wire a resistor in. But I don't know where/how. Or if it is even wired correctly to start.
Any help would be greatly appreciated.
Thank you!
