good luck with that. those are so vague. i will be honest with you with the amount of knowledge you seem to have of wiring i dont think a motor swap from a supra to your astro is in your capabilities.
you have to understand certain things about the wiring and how certain things function as in the computer and sensors and gauges. it is not all just plug power from here into your toyota computer and so on. sometimes there is custom computer programming involded and such. it is not plug and play like a 350 with a carb and an hei distributor and one wire alternator. it is a bit more complex.
i am not trying to be a dick i am just given you the reality of your situation...
