Lookin to swap the s5 TII into the s4 NA chasis and was wondering if it was best to get an S5 harness. Ive spliced before but from what i read theres a lot of differences between harnesses. Do i need a new clutch master cylinder? If anybody's got any links that would be cool. I plan on going premix and heard you can leave the OMP in the plug but not running and wont get limp mode. ANy pointers on the swap. Is this a good swap or should i loose a couple of hp and go S4 TII.
