So I finally got my SLA Adapter,
Installed it with taps into the back of the Cluster and coded it, didn't work. was raging.... Cutting a long story short, the wiretaps were shit. So I cut the CANH, CANL, +12v, and ground, soldered the emulator into the lines, silicone and heatsinked them, followed by using wire harness strapping, then 3M the emulator onto the back of the cluster. Looks a pro job, you'd never know its aftermarket and works great! MPH FTW.
