This is a thread for the guys who have done the xr6 turbo conversions into the e series vehicles. does anyone actually have a wiring diagram or a list of what is needed to run the ba ecu with the earlier cars? I would imagine that not all the wiring would be required? I understand that getting tacho and speedo requires aftermarket parts which looks easy enough to fit. my issue seems to be the wiring up of the BA computer to run.

Or is it better to get an aftermarket computer and run the motor that way? Vehicle is an EL XR6.
Cheers
