Wiring questions : Temp gauge and tach

[92yukon]

Got my engine swapped in (2005 5.3 into 96 Tahoe) and its running just need to finish up on some wiring now. Got 2 questions, which temp sender is for the temp gauge on the dash, the 1 wire sender that was in the 5.7 head or the 2 wire that was in the thermostat housing ? Then where do i tap in for my tach signal, is there a wire coming out of the 96 pcm i can use ?

Anybody ? I figured out the temp sending unit for the gauge it's the 1 wire sender in the head just in case someone else stumbles across this during a search. There has to be someone on this forum with a working tach who can tell me where in the engine compartment I can find the wire or if I have to pull the cluster out.

Try the white wire coming from the ignition coil.

Try this place http://bbbind.com/tech_database.html They have what you are looking for in terms of where to tap in for your tach, but you will have to do a little digging. Good luck.
