I have a 89 K1500 that I did a lq4/4l80e swap. I used a holley terminator x max and all works very well except the Cruise. Not sure if it worked before the swap. I replaced the stalk with a new delco unit. I've followed all diagnostic flow charts in the manual and still have no Cruise. The drac is build into the IP cluster as I added dip switches to get the proper calibration after gears and tires. The speedo is dead nuts as in comparison to what the holley handheld is seeing as far as speed. I'm at a loss and have a few questions.
1. Will the Cruise work without the stock ecm? I have verified while troubleshooting I am getting a buffer signal to the module from the IP.
2. This one is silly but must be asked, what is the minimum speed to assert Cruise?
3. I already have went to the junkyard to get a new module. I got one off a gmt800, they look almost identical. Should that work or do I need one off a gmt400?
