My engine has a T88 on a HKS manifold, sits dead center of the strut pillar and hit hard. i will have to end up notching the pillar about a half inch to get the turbo to clear. I think the t04R is alittle bit smaller housing but not sure. with a manual you can put a little less tilt in the motor and get it to clear. Im running an auto tranny and the pan needs to be horizontal so i will be cutting the pillar to get it in there. Sorry cant help you with the wiring i have run nothing but standalones.
