Wiring Question

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.

Its all plug n play. You dont even need the type r harness. U can use the gsr one. Either way both are just fine. Get rid of the obd2 ecus and go with the obd1 gsr or a chipped si/ex ecu. OF course you'll need the skunk2 obd2 to obd1 jumper harness. Just a suggestion.:smile:
