TPS sensor, air temp sensor, coolant temp sensor, fuel pump relay (comes with the Microtech), wiring, some fuses, CAS, O2 sensor (though not required). I think that's all the "required" off the top of my head.

Edit...Why not use the LT-8(s) instead of the X version and use the stock ignition coils?

wouldnt wiring the stock coils in a 1st gen be a lot harder than just using four coils?

Oh, 1st gen. Well, that changes things. You could also get the 2nd gen coil packs. Might be cheaper then the Bosch units, and just as good. The 2nd gen ignition is excellant. Has some high RPM breakup, but most fix that with a CDI box on the leading.

Stock coils sell for what? 60 bucks a set. The Bosh coils go for around 55 each and you need four. If you are on a budget go with stock!

Yep.

coolant temp in the radiator?
On the block under the oil pressure sender.

what is the CAS again?
Front cover, right side where the dizzy would go on earlier engines.

and where does the air temp sensor go?
Elbow before the throttle body where the IC connects.

I've wired a bunch of them, though never under ideal circumstances (at the side of a track, in a rainy/foggy parking lot, in an emergency in a garage desperately trying to get to Revolution, etc.). If you can solder, and understand the basics, then wiring is not hard. The manual pretty much covers it.

The basics, as in how a basic electrical circuit is made, how to solder PROPERLY, use heat shrink, etc. The manual has the pinouts for all the stock sensors, and all the wires on the Microtech harness are clearly marked.

Well, a step by step Microtech install is a little beyond what I am willing to type, but if you can install a stereo, then the Microtech shouldn't be hard. As with all standalones, the real work is in the tuning.

If I am not mistaken, the Microtech site has all the wiring diagrams on their website:
