How do you mate a drive-by-wire GTO pedal to the BMW pedal in an E36 LS2 swap?

Here is what the documentation says. Each point links to its source; details depend on your exact computer, harness and transmission.

• LTx: Holley's Terminator X Max also supports the same GM pedal 10379038 for GM LTx applications with throttle bodies 12617792 and 12678223, so one pedal part number covers both LSx and LTx combos. (Holley)
• Holley requires the DBW accelerator pedal to have adequate clearance through its full travel, to be mounted away from the brake pedal and positioned lower than the brake pedal when the brake is depressed, and to be solidly mounted. (Holley)
• For a GTO pedal transplanted into a different chassis (such as a BMW E36), Holley's guidance is that the DBW pedal must be solidly mounted with adequate clearance through its full travel, positioned away from and lower than the brake pedal when the brake is depressed. (Holley)
• The Lokar BDBW-GM06 is a complete drive-by-wire kit including an electronic control module, wiring harness, and accelerator pedal assembly; it is compatible with GM pedal assemblies 10379038, 10367117, 22741799, 22741800, and 921199239 and is aimed at LS and modern GM engine swaps. (Autoplicity)
