Did some searching and didn't quite find the info I needed. I have an 89 Cheyenne with the 2 gauge cluster (only fuel and speed). I'm not really trusting the computer to tell me when it's over heating, so I picked up a 5 gauge cluster from a 90. How plug and play is this going to be? Where do I look to see if I'm prewired for the additional gauges and that the sending units for voltage/oilpressure/coolant temp are?
