Fcd
so....how and where do i install one on my new 87 T2? i just ordered a turbo-back RB exhaust and now, i need to know where to hook up an FCD. 
...i searched btw, and i came up with tons of other posts, but none with one about where to hook in the plugs.

unplug the map sensor
plug the fcd into that
plug the harness into the other connector on the fcd
but don't use the RB turbo-back with an fcd unless you add fuel and take timing out. you'll go boom with haste.

the turbo back is going to cause you to boost creep.
port the wastegate, back off on the timing 1* for every pound of boost over 8psi, double check the afr's with a wideband, and probably either add 680 secondaries, or at least an safc.
lots of guys have done that combo--adds gobs of HP over a stock car, but you'll be running too lean with too much timing.
