I've just put my built 2004 RXP engine into an 08 RXP-X hull that I had. Everything went in fine except for the wiring harness has about 4 connectors that can't be used. After some research it looks like I'll have to be changing some stuff on the motor.

The ECU I'm using is a RIVA with the anti theft turned off, I have the X charger and injectors already.

I have both wiring harness's on hand 2008 RXP harness and the 2004 Harness.

The Carbon seal boot is compressed more than normal. This is probably due to the fact that the pump tunnel is a bit longer on the X. Is this okay? I'm currently running the original X driveshaft.

What do I need to make this all work and retain the 2008 Digital gauges?
