ENGINE SWAP: GSR to Type R help!

Hi guys, I wanted to know a little bit about wiring. I just got a Type R to put into my GSR. Motor is same year and everything. The Type R came w/ wires up to the firewall, there is a harness there. I want to know if I can plug that directly into the harness comeing out of the gsr firewall. And just swap out the ecus. So therefor the wiring from ECU to the firewall will remain the GSR's original wires. Please inform me.

Email me at [email protected] if you can. I'm not sure if this forwards to there or not.

where did you get your type r motor?
how much did you get it for?
