Started my FAST XFI XIM install...

[BLK WS6]

I have started to install a FAST XFI and XIM system while maintaining the stock PCM to run items like the stock gauges. The main idea is to pull all sensors no longer needed (unpin from the stock harness) on the stock pcm, separate the XFI wiring harness and combine into one single harness.

Has anyone on here done this install? Any tips?

I've done this with a classic FAST EFI in my Caprice.

Take your time, label everything, double and triple check all your connections to make sure you have the right wires connected together.
After a while all the wires look the same and it's easy to mix them up... :p
