Watertemp gauge Alright so i'm looking to getting a new gauge that i want to install and i'm pretty shure i can do all the install my self the only question i have is can i just pull out hte old water temp sensor and replace it with a new sending unit like for the auto meter gauges? or do i have to tap into some where else?
water temp sensor - the information to the gauge cluster is in serial data, so you cannot tap into it. you can not use the temp gauge on the driver side head as it is used by the PCM (99+ LS1's). one option is to use the plug on rear of the passenger side head, BUT you need to get an adapter that does not come with the autometer gauge. this is autometer p/n 2277 1/8NPT to 12X1.5mm, but you must also drill out to fit sender. you can then use the existing location towards the back of the passenger head to screw in the sending unit. BE CAREFUL as it is easy to break. you will then have to run a wire to the gauge through the firewall from there.
there are other adapters that are the same thread out there, but they are CRAP. they break very easily. I broke two before i got the autometer adapter.
i got this info from here

EDIT- just remember to drill the hole favoring the side away from the throttle body, or else the brass fitting might interfere with the linkage.
