As for the tach, they will work with the output from the PCM, but you will need to change the 'tach resolution' in the tune from 6 to 3. LS engines run on a 4 cylinder mode and changing the resolution will double it to an 8 cylinder.

The temp sender has been the topic of MANY threads, but what I usually do if keeping the stock gauge is to use the stock sender that was made for it. This requires drilling and tapping the head to accept the larger sender, but it's not all that hard to do and it's the best way to assure the gauge is going to be accurate.
Cool, I had a feeling I was going to have to tap the head. I was thinking of putting a bung in the radiator, but that's not as fail safe as monitoring actual engine temp on the other side of the t-stat. Sent the payment lastnight and will post some pics when I get working on the cluster, hopefully sooner then later.
Thanks again,
Curt
