I thought i would share this with all of you. This is my custom made patch harness which allows me to run my dsm link in both my 1g and 2g using the same ecu. The credit goes to quentin marchone, he did an amazing job.

Very nice work! Have you tested it out yet?
 
Im waiting for results on my work as I didnt have a 2g to test it out in :(. I did take about 2 weeks of R&D on schematics and RRE for the CAS wiring he did on his car already. I just wired the CAS 1g wires to the way RRE has theres set up.

The black nubs of wires are for emissions, ac, and that sort of junk that he dont have anymore. But everything is wired to work with all the factory readouts like the CEL, tachometer.

When you go for a test drive tomarrow on the trans please call or text me on how well the trans does after I rebuilt it last night. I like to hear that my work is done properly and everything works as it should.
 
Ok so here are the results. I drove the car and everything works as it should the only thing I have to do is hardwire the fan since the 1g ecu cannot fully control the fans, I also need to install a 1g knock sensor. Other then those little bugs everything works. 2 step, antilag, narrowband sim and all the other features work. Ill post some more pics and videos after I fix the little bugs and tune the car.
