sc300NJ

well in the coarse of a year and some odd months of owning my sc300. im almost done swapping my 2jzge powered car with an auto into a 2jzgte powered soarer r154 tranny beast. it took 11 months to do this out of owning the car. so i really didnt get to drive and spend time with the car.Not to mention it costed me thriple the amount of money this should of costed from what i hear on this site and others. as pissed as i am atleast the car is almost done, maybe this wednesday 2/13. now the problem. i went stadalone ecu (Wolf V500). now going stadalone i know you automatically lose A/C and your center console gauges and the cluster some other stuff here and there. but anyone who used this ecu or maybe a aem ems one how did you hook up the heat for the car and do the gauges? for the tach and the speedo do i really need a tach adapter from msd or some other company. any help for these questions would be great. i dont want to spend anymore money then is needed. thanks to all at CL.
