HAS ANYONE USED A RALLY PAC CLUSTER ON AN LS SWAP?

[20Grand]

I currently have an LS swap with aftermarket gauges- oil, battery and temp. I just got a rally pac cluster. Can I simply cut the wires from the gauges I have working now and splice them into the rally cluster? Also, how would I get the tachometer to work on a 4l60e? Engine is a 2005 5.3 Silverado and the trans is from a 2003 Yukon.

What?
No,you can't use the LS or aftermarket sending units for the Rally Pak. You need to run the factory sending units for factory gauges.

If using the factory temp and oil psi sensors it’ll work but tachometer and speedometer are your biggest challenges. If your going to use a modern transmission you need to buy a VSS to mechanical cable adapter which run around $400 last time I checked. I bought Dakota digital...problem solved

This...I converted my SS to electronic for $10. PCM RED 10 is the Tach output. Simple stuff guys.

Pretty sure that Rally Pack had the same speedo unit as the MCSS. I know someone who has done what I did there based off of my thread in that link and theirs worked.
