 Cluster Swap
The car does not have an on-board computer.
Whats in the car now for what the BMW TI schematic say is the mpg circuit is:
From DME pin 42 on green/red wire to connector X6031 pin 3 from there on green/red wire to A2W (cluster) blue connector X17 pin 13. I'm not sure why its there because the car did not come with the mpg gauge.
I'm thinking I would need to compare TI's X17 plug breakout to the M3's X17 breakout to learn if they are different. OR since we are swapping the engine soon I Just wait to put the 6cyl wiring harness and DME in.
My fear is before we change the harness with the gauge burying itself forcefully to 0 mpg it may burn up |
