67-72 Tach dash
Anyone running the factory tach dash with an LSX 60/80E combo? I've got a awesome 72 dash set up i bought for my truck and i want to use it. And i'm an electronics moron.
Nothing in the search for 67-72. Thanks

Re: 67-72 Tach dash
I'm compiling info, and reading up on this swap. But I didn't see any info in the stock tach dash (67-72) being used and if it would work.
When I do my swap I want to use my new tach dash. Posted via Mobile Device

Re: 67-72 Tach dash
Depends on what year your PCM is, but generally the 2003 and newer will need the pull up resistor. Also you'll have to change the tach resolution from 6 to 3 in the tune to make it read correctly since LS motors use a 4 cylinder signal, otherwise it will read half of what it's running (on a V8 tach). Other than that, just hook up the ignition wire like it was originally and hook the signal wire, the one that went to the coil, to the tach output out of the PCM, generally a white wire at C2 10, but that may depend on year and application.
