If the AHC delete was done properly including the fuses and wiring delete then you shouldn't have any lights coming on. There are threads on here that walk you through this. If I recall, there's a fuse in the engine bay and in the cab plus a wire or plug removal under the step wheel.
Did an AHC delete and this is what's left over.
Here's a list with prices:
Front AHC shocks - $150
4 AHC accumulator globes - $100 - SOLD
AHC pump assembly with reservoir - $100
PM me with any questions.
