okay just a question about the t2 coils, crank sensor and air temp sensor...does it matter which FC year wise these come from...and will they fit my 12at?

for all those items, they're the same from 86-92.

it might be just a little tricky wiring up the trailing coils from scratch if you've never doen it before, but there's lots of writeups in various places, and you can always ask here or email me and i'll help you out the best i can.

crank sensor should drop right in where your distributor went, you'll have to drill and tap for the air temp sensor. if your car has a coolant sensor (a real one--not for the gauge) that'll probably work, otherwise, use one from an fc.

coils will work just as long as you can find a place to mount them. yellow wire on your trailing coil is your tach output...your leading has a black wire.

throttle position sensor...hmmm. you need one, so get creative.
i think you can probably use the haltech tps with the microtech if you can find a way to mount it, but double check me on that.
