How'd you get engine temp off of that pinout chart?

[oldcarstulsa]

it works off the serial data, only the oil pressure has its own wire

[airdeano]

the fuel gauge is also serial data. youll need a 250ohm sending unit
in the tank. wire the sending unit to the PCM.

So how many ohms is the stock 2004 sending unit?

[Chuck21387]

Serial data? So i can't just tap onto all my sensors and hook them up to my factory jeep electronic gauges huh....i have to get a chevy cluster? i think i'll figure out how to get signals from other sensors...maybe double up on sensors...your thoughts?

Double the sensors. That works great. I've done it twice now and I have no regrets. What's nice is I can hook HPT or any scanner to my OBDII port and double check their readings.
